fix: memory leak in session removal - close MCP server properly (#471 )

- Add close() method to N8NDocumentationMCPServer that: - Calls server.close() (MCP SDK cleanup) - Clears internal cache - Nullifies service references to help GC - Update removeSession() to call server.close() before releasing references Root cause: removeSession() deleted server from map but didn't call cleanup Evidence: Production server memory grew ~1GB in 43 minutes (10% to 35%) Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
