chore: bump version to 2.22.6

Version bump to trigger automated release workflow with YAML fix.

This version bump combined with the YAML syntax fix will:
- Trigger the release workflow (version 2.22.5 → 2.22.6)
- Test the complete release pipeline end-to-end
- Publish v2.22.6 to npm registry
- Create GitHub release v2.22.6
- Build and push Docker images

Previous versions 2.22.4 and 2.22.5 failed to publish due to YAML parsing
errors in the release workflow (resolved in previous commit).

-
-**sql.js Fallback: Fixed Database Health Check Crash**
-
-Fixed critical startup crash when the server falls back to sql.js adapter (used when better-sqlite3 fails to load, such as Node.js version mismatches between build and runtime).
-
-#### Problem
-
-When Claude Desktop was configured to use a different Node.js version than the one used to build the project:
-- better-sqlite3 fails to load due to NODE_MODULE_VERSION mismatch (e.g., built with Node v22, running with Node v20)
-- System gracefully falls back to sql.js adapter (pure JavaScript, no native dependencies)
-- **BUT** the database health check crashed with "no such module: fts5" error
-- Server exits immediately after startup, preventing connection
-
-**Error Details:**
-```
-[ERROR] Database health check failed: Error: no such module: fts5
-    at e.handleError (sql-wasm.js:90:371)
-    at e.prepare (sql-wasm.js:89:104)
-    at SQLJSAdapter.prepare (database-adapter.js:202:30)
-    at N8NDocumentationMCPServer.validateDatabaseHealth (server.js:251:42)
-```
-
-**Root Cause:** The health check attempted to query the FTS5 (Full-Text Search) table, which is not available in sql.js. The error was not caught, causing the server to exit.
-
-#### Solution
-
-Wrapped the FTS5 health check in a try-catch block to handle sql.js gracefully:
-
-```typescript
-// Check if FTS5 table exists (wrap in try-catch for sql.js compatibility)
-try {
-  const ftsExists = this.db.prepare(`
-    SELECT name FROM sqlite_master
-    WHERE type='table' AND name='nodes_fts'
-  `).get();
-
-  if (!ftsExists) {
-    logger.warn('FTS5 table missing - search performance will be degraded...');
-  } else {
-    const ftsCount = this.db.prepare('SELECT COUNT(*) as count FROM nodes_fts').get();
-    if (ftsCount.count === 0) {
-      logger.warn('FTS5 index is empty - search will not work properly...');
-    }
-  }
-} catch (ftsError) {
-  // FTS5 not supported (e.g., sql.js fallback) - this is OK, just warn
-  logger.warn('FTS5 not available - using fallback search. For better performance, ensure better-sqlite3 is properly installed.');
-}
-```
-
-#### Impact
-
-**Before Fix:**
-- ❌ Server crashed immediately when using sql.js fallback
-- ❌ Claude Desktop connection failed with Node.js version mismatches
-- ❌ No way to use the MCP server without matching Node.js versions exactly
-
-**After Fix:**
-- ✅ Server starts successfully with sql.js fallback
-- ✅ Works with any Node.js version (graceful degradation)
-- ✅ Clear warning about FTS5 unavailability in logs
-- ✅ Users can choose between sql.js (slower, works everywhere) or rebuilding better-sqlite3 (faster, requires matching Node version)
-
-#### Performance Notes
-
-When using sql.js fallback:
-- Full-text search (FTS5) is not available, falls back to LIKE queries
-- Slightly slower search performance (~10-30ms vs ~5ms with FTS5)
-- All other functionality works identically
-- Database operations work correctly
-
-**Recommendation:** For best performance, ensure better-sqlite3 loads successfully by matching Node.js versions or rebuilding:
-```bash
-# If Node version mismatch, rebuild better-sqlite3
-npm rebuild better-sqlite3
-```
-
-#### Files Changed
-
-**Modified (1 file):**
-- `src/mcp/server.ts` (lines 299-317) - Added try-catch around FTS5 health check
-
-#### Testing
-
-- ✅ Tested with Node v20.17.0 (Claude Desktop version)
-- ✅ Tested with Node v22.17.0 (build version)
-- ✅ Server starts successfully in both cases
-- ✅ sql.js fallback works correctly with graceful FTS5 degradation
-- ✅ All 6 startup checkpoints pass
-- ✅ Database health check passes with warning

-
-### 📝 Documentation Fixes
-
-**Issue #292: Corrected Array Property Removal Documentation in n8n_update_partial_workflow**
-
-Fixed critical documentation error in property removal patterns that could have led users to write non-functional code.
-
-#### Problem
-
-The documentation incorrectly showed using array index notation `[0]` for removing array elements:
-```javascript
-// INCORRECT (doesn't work as shown)
-updates: { "parameters.headers[0]": undefined }
-```
-
-**Root Cause**: The `setNestedProperty` implementation doesn't parse array index notation like `[0]`. It treats `headers[0]` as a literal object key, not an array index.
-
-**Impact**: Users following the documentation would write code that doesn't behave as expected. The property `headers[0]` would be treated as an object key, not an array element reference.
-
-#### Fixed
-
-**Three documentation corrections in `src/mcp/tool-docs/workflow_management/n8n-update-partial-workflow.ts`:**
-
-1. **Nested Property Removal Section** (lines 236-244):
-   - Changed comment from `// Remove array element` to `// Remove entire array property`
-   - Changed code from `"parameters.headers[0]": undefined` to `"parameters.headers": undefined`
-
-2. **Example rm5** (line 340):
-   - Changed comment from `// Remove array element` to `// Remove entire array property`
-   - Changed code from `"parameters.headers[0]": undefined` to `"parameters.headers": undefined`
-
-3. **Pitfalls Section** (line 405):
-   - OLD: `'Array element removal with undefined removes the element at that index, which may shift subsequent indices'`
-   - NEW: `'Array index notation (e.g., "parameters.headers[0]") is not supported - remove the entire array property instead'`
-
-#### Correct Usage
-
-**To remove an array property:**
-```javascript
-// Correct: Remove entire array
-n8n_update_partial_workflow({
-  id: "wf_012",
-  operations: [{
-    type: "updateNode",
-    nodeName: "HTTP Request",
-    updates: { "parameters.headers": undefined }  // Remove entire headers array
-  }]
-});
-```
-
-**NOT:**
-```javascript
-// Incorrect: Array index notation doesn't work
-updates: { "parameters.headers[0]": undefined }  // Treated as object key "headers[0]"
-```
-
-#### Impact
-
-- **Prevents User Confusion**: Clear documentation on what works vs. what doesn't
-- **Accurate Examples**: All examples now show correct, working patterns
-- **Better Error Prevention**: Pitfall warning helps users avoid this mistake
-- **No Code Changes**: This is purely a documentation fix - no implementation changes needed
-
-#### Testing
-
-- ✅ Documentation reviewed by code-reviewer agent
-- ✅ Tested by n8n-mcp-tester agent
-- ✅ All examples verified against actual implementation behavior
-- ✅ Pitfall accurately describes technical limitation
-
-#### Files Changed
-
-**Documentation (1 file)**:
-- `src/mcp/tool-docs/workflow_management/n8n-update-partial-workflow.ts` - Corrected 3 instances of array property removal documentation
-
-**Configuration (2 files)**:
-- `package.json` - Version bump to 2.22.7
-- `package.runtime.json` - Version bump to 2.22.7
-
-#### Related
-
-- **Issue**: #292 - Missing documentation on how to remove node properties using `updateNode`
-- **PR**: #375 - Resolve GitHub Issue 292 in n8n-mcp
-- **Code Review**: Identified critical array index notation documentation error
-- **Root Cause**: Implementation doesn't parse array bracket notation `[N]`

-## [2.22.6] - 2025-10-25
-
-### 🐛 Bug Fixes
-
-**Issue #228: Fix Docker Port Configuration Mismatch**
-
-Fixed critical Docker configuration bug where custom PORT environment variable values were not properly mapped to container ports, causing connection failures in Docker deployments.
-
-#### Problem
-- **docker-compose.yml**: Port mapping `"${PORT:-3000}:3000"` hardcoded container port to 3000
-- **docker-compose.yml**: Health check hardcoded to port 3000
-- **Dockerfile**: Health check hardcoded to port 3000
-- Impact: When PORT≠3000 (e.g., PORT=8080), Docker mapped host port to wrong container port
-
-#### Solution
-- **docker-compose.yml line 44**: Changed port mapping to `"${PORT:-3000}:${PORT:-3000}"`
-- **docker-compose.yml line 56**: Updated health check to use dynamic port `$${PORT:-3000}`
-- **Dockerfile line 93**: Updated HEALTHCHECK to use dynamic port `${PORT:-3000}`
-- **Dockerfile line 85**: Added clarifying comment about PORT configurability
-
-#### Testing
-- Verified with default PORT (3000)
-- Verified with custom PORT (8080)
-- Health checks work correctly in both scenarios
-
-#### Related Issues
-- Fixes #228 (Docker Compose port error)
-- Likely fixes #109 (Configuration ignored in HTTP mode)
-- Likely fixes #84 (Can't access container)

-# 1. CHECK EXISTING RELEASES FIRST (prevents version conflicts!)
-gh release list | head -5
-# Look at the latest version - your new version must be higher!
-
-# 2. Switch to main and pull
-git checkout main && git pull
-
-# 3. Check for updates (dry run)
-npm run update:n8n:check
-
-# 4. Run update and skip tests (we'll test in CI)
-yes y | npm run update:n8n
-
-# 5. Create feature branch
-git checkout -b update/n8n-X.X.X
-
-# 6. Update version in package.json (must be HIGHER than latest release!)
-# Edit: "version": "2.XX.X" (not the version from the release list!)
-
-# 7. Update CHANGELOG.md
-# - Change version number to match package.json
-# - Update date to today
-# - Update dependency versions
-
-# 8. Update README badge
-# Edit line 8: Change n8n version badge to new n8n version

 ## Tips
 
-- If you're running n8n locally, use `http://localhost:5678` as the `N8N_API_URL`.
+- If you're running n8n locally, use `http://localhost:5678` as the N8N_API_URL
-- The n8n API credentials are optional. Without them, you'll only have access to documentation and validation tools. With credentials, you get full workflow management capabilities.
+- The n8n API credentials are optional - without them, you'll have documentation and validation tools only
-- **Scope Management:**
+- With API credentials, you'll get full workflow management capabilities
-    - By default, `claude mcp add` uses `--scope local` (also called "user scope"), which saves the configuration to your global user settings and keeps API keys private.
+- Use `--scope local` (default) to keep your API credentials private
-    - To share the configuration with your team, use `--scope project`. This saves the configuration to a `.mcp.json` file in your project's root directory.
+- Use `--scope project` to share configuration with your team (put credentials in environment variables)
-- **Switching Scope:** The cleanest method is to `remove` the server and then `add` it back with the desired scope flag (e.g., `claude mcp remove n8n-mcp` followed by `claude mcp add n8n-mcp --scope project`).
+- Claude Code will automatically start the MCP server when you begin a conversation
-- **Manual Switching (Advanced):** You can manually edit your `.claude.json` file (e.g., `C:\Users\YourName\.claude.json`). To switch, cut the `"n8n-mcp": { ... }` block from the top-level `"mcpServers"` object (user scope) and paste it into the nested `"mcpServers"` object under your project's path key (project scope), or vice versa. **Important:** You may need to restart Claude Code for manual changes to take effect.

-## Removing Properties with undefined
-
-To remove a property from a node, set its value to \`undefined\` in the updates object. This is essential when migrating from deprecated properties or cleaning up optional configuration fields.
-
-### Why Use undefined?
-- **Property removal vs. null**: Setting a property to \`undefined\` removes it completely from the node object, while \`null\` sets the property to a null value
-- **Validation constraints**: Some properties are mutually exclusive (e.g., \`continueOnFail\` and \`onError\`). Simply setting one without removing the other will fail validation
-- **Deprecated property migration**: When n8n deprecates properties, you must remove the old property before the new one will work
