* perf: optimize workflow tool responses for token efficiency (v2.29.0)
Reduce response sizes by 75-90% for 4 workflow management tools:
- n8n_update_partial_workflow: Returns {id, name, active, operationsApplied}
- n8n_create_workflow: Returns {id, name, active, nodeCount}
- n8n_update_full_workflow: Returns {id, name, active, nodeCount}
- n8n_delete_workflow: Returns {id, name, deleted: true}
AI agents can use n8n_get_workflow with mode 'structure' if they need
to verify the current workflow state after operations.

Integration tests now verify minimal response format and use
client.getWorkflow() to fetch actual workflow state for verification.

- 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%)
