fix: Implement warm start pattern for session restoration (v2.19.5)

Browse Source

Fixes critical bug where synthetic MCP initialization had no HTTP context
to respond through, causing timeouts. Implements warm start pattern that
handles the current request immediately.

Breaking Changes:
- Deleted broken initializeMCPServerForSession() method (85 lines)
- Removed unused InitializeRequestSchema import

Implementation:
- Warm start: restore session → handle request immediately
- Client receives -32000 error → auto-retries with initialize
- Idempotency guards prevent concurrent restoration duplicates
- Cleanup on failure removes failed sessions
- Early return prevents double processing

Changes:
- src/http-server-single-session.ts: Simplified restoration (lines 1118-1247)
- tests/integration/session-restoration-warmstart.test.ts: 9 new tests
- docs/MULTI_APP_INTEGRATION.md: Warm start documentation
- CHANGELOG.md: v2.19.5 entry
- package.json: Version bump to 2.19.5
- package.runtime.json: Version bump to 2.19.5

Testing:
- 9/9 new integration tests passing
- 13/13 existing session tests passing
- No regressions in MCP tools (12 tools verified)
- Build and lint successful
