Sync from Docs

When invoked by the sync workflow, the Docs repo is checked out at _docs/. Your job:

1. Source of truth — _docs/openapi/flux.json is the OpenAPI spec for the FluxMCP API.
2. Compare models — The Literal types in core/types.py must match the spec's model enum. Add/remove as needed.
3. Compare parameters — Each @mcp.tool() function's parameters should match the corresponding OpenAPI endpoint.
4. Update defaults — If a new model becomes the recommended default, update the default in core/types.py.
5. Update README — Keep the model table and feature list current.
6. Add tests — For new tools or parameters, add test cases in tests/.
7. PR title — Use format: sync: <description> [auto-sync]
