- Add extensions field to HTTPRoute class to store x-* fields
- Extract extensions from operation's model_extra in parser
- Add test to verify extensions are properly parsed
Because the server now validates inputs, its no longer viable to provide a JSON string where e.g. an array is expected, so we can entirely remove FastMCP's "legacy json parsing" support from 1.x.
This is a breaking change (for legacy opt-in behavior)
Fixes breaking changes from mcp-python-sdk PR #982 which updated
BearerAuthBackend to use TokenVerifier protocol instead of OAuth providers.
Changes:
- Add verify_token() method to BearerAuthProvider implementing TokenVerifier protocol
- Add verify_token() method to InMemoryOAuthProvider implementing TokenVerifier protocol
- Update BearerAuthBackend usage in setup_auth_middleware_and_routes() to pass TokenVerifier
- Add comprehensive unit tests for TokenVerifier implementations
- Add integration tests for BearerAuthBackend with TokenVerifier
- Add tests for HTTP auth setup functions
All existing functionality preserved with full backwards compatibility.

Previously, external schema references (URLs) in OpenAPI schemas were
silently passed through and only failed during JSON schema validation
with confusing "failed to match exactly one schema" errors.
This change:
- Detects external references in _replace_ref_with_defs() and raises clear error messages
- Updates exception handlers to propagate external reference errors while preserving other error handling
- Adds comprehensive test coverage for external reference detection
- Provides helpful error messages explaining that FastMCP only supports local schema references
