- Fixed docker-entrypoint.sh to use NODE_DB_PATH instead of hardcoded paths
- Added log_message() helper to prevent stdio mode output corruption
- Fixed directory creation race condition with proper ownership
- Added path validation to ensure NODE_DB_PATH ends with .db
- Updated rebuild.ts to respect NODE_DB_PATH environment variable
- Added comprehensive documentation for custom database paths
- Bumped version to 2.7.16
The bug was caused by hardcoded /app/data/nodes.db paths in the Docker
entrypoint script that ignored the NODE_DB_PATH environment variable.

- Remove default settings logic from cleanWorkflowForUpdate that was causing
"settings must NOT have additional properties" error
- The function now only removes read-only fields without adding any properties
- Add comprehensive test coverage in test-issue-45-fix.ts
- Add documentation explaining the difference between create and update functions
- Bump version to 2.7.14
This fixes the issue where n8n_update_partial_workflow would pass validation
but fail during execution when workflows didn't have settings defined.

- Add FTS5 pre-creation in fetch-templates.ts before data import
- Create prebuild-fts5.ts script to ensure FTS5 tables exist
- Improve logging in template-repository.ts for better debugging
- Add npm script 'prebuild:fts5' for manual FTS5 setup
This ensures template search works consistently in Docker mode
where runtime FTS5 table creation might fail due to permissions.

Root cause: AI agents were placing error handling properties inside `parameters` instead of at node level
Major changes:
- Enhanced workflow validator to check for ALL node-level properties (expanded from 6 to 11)
- Added validation for onError property values and deprecation warnings for continueOnFail
- Updated all examples to use modern error handling (onError instead of continueOnFail)
- Added comprehensive node-level properties documentation in tools_documentation
- Enhanced MCP tool documentation for n8n_create_workflow and n8n_update_partial_workflow
- Added test script demonstrating correct node-level property usage
Node-level properties now validated:
- credentials, disabled, notes, notesInFlow, executeOnce
- onError, retryOnFail, maxTries, waitBetweenTries, alwaysOutputData
- continueOnFail (deprecated)
Validation improvements:
- Detects misplaced properties and provides clear fix examples
- Shows complete node structure when properties are incorrectly placed
- Type validation for all node-level boolean and string properties
- Smart error messages with correct placement guidance

The SecureKeyGuard alert was a false positive (mistaking "validate_workflow"
for "VAULT_TOKEN"), but the review uncovered actual hardcoded credentials
that have now been removed.

- Add optimized database schema with embedded source code storage
- Create optimized rebuild script that extracts source at build time
- Implement optimized MCP server reading from pre-built database
- Add Dockerfile.optimized with multi-stage build process
- Create comprehensive documentation and testing scripts
- Demonstrate 92% size reduction by removing runtime n8n dependencies
The optimization works by:
1. Building complete database at Docker build time
2. Extracting all node source code into the database
3. Creating minimal runtime image without n8n packages
4. Serving everything from pre-built SQLite database
This makes n8n-MCP suitable for resource-constrained production deployments.
