* fix: use correct MCP SDK API for server capabilities in test
getServerVersion() returns Implementation (name/version only), not the
full init result. Use client.getServerCapabilities() instead to access
server capabilities, fixing the CI typecheck failure.

* fix: resolve multiple n8n_update_partial_workflow bugs (#592, #599, #610, #623, #624, #625, #629, #630, #633)
Phase 1 - Data loss prevention:
- Add missing unary operators (empty, notEmpty, exists, notExists) to sanitizer (#592)
- Preserve positional empty arrays in connections during removeNode/cleanStale (#610)
- Scope sanitization to modified nodes only, preventing unrelated node corruption
- Add empty body {} to activate/deactivate POST calls to fix 415 errors (#633)
Phase 2 - Error handling & response clarity:
- Serialize Zod errors to readable "path: message" strings (#630)
- Add saved:true/false field to all response paths (#625)
- Improve updateNode error hint with correct structure example (#623)
- Track removed node names for better removeConnection errors (#624)
Phase 3 - Connection & type fixes:
- Coerce sourceOutput/targetInput to String() consistently (#629)
- Accept numeric sourceOutput/targetInput at Zod schema level via transform
Phase 4 - Tag operations via dedicated API (#599):
- Track tags as tagsToAdd/tagsToRemove instead of mutating workflow.tags
- Orchestrate tag creation and association via listTags/createTag/updateWorkflowTags
- Reconcile conflicting add/remove for same tag (last operation wins)
- Tag failures produce warnings, not hard errors

* fix: resolve pre-existing integration test failures in CI
- Create new MCP Server instance per connection in test helpers (SDK 1.27+
requires separate Protocol instance per connection)
- Normalize database paths with path.resolve() in shared-database singleton
to prevent path mismatch errors across test files
- Add no-op catch handler to deferred initialization promise in server.ts
to prevent unhandled rejection warnings
- Properly call mcpServer.shutdown() in test helper close() to release
shared database references

* fix(ci): update MCP SDK version check from 1.20.1 to 1.27.1
The dependency-check workflow was hardcoded to expect MCP SDK 1.20.1,
causing CI failure after the intentional upgrade to 1.27.1.

* fix(tests): close existing connection before reconnecting in MCP protocol tests
MCP SDK 1.27+ enforces single-connection per Server instance, throwing
"Already connected to a transport" when connect() is called twice.
Updated test helper to close existing connections before reconnecting.
