🐛 Fix double JSON parsing from request body
Remove the 'await request.json()' call which was inadvertently left in the routing path. This ensures that the body bytes are passed directly to Pydantic's validate_json via FastAPIOptimizedJsonBytes, bypassing unnecessary Python dict allocations entirely.

⚡ Cache pydantic.v1 import to minimize compatibility overhead
Moving the import of pydantic.v1 and the warnings filter to the module level avoids executing them on every single object serialization in jsonable_encoder, significantly boosting performance for Pydantic v1 backward compatibility checks.

✨ Optimize request parameter validation via synthetic models
Group validation of multiple parameters (query, path, headers, cookies) into a single Pydantic call using a dynamically generated BaseModel.
- Introduce get_grouped_adapter with lru_cache to cache synthetic models
- Replace individual parameter validation loop with validate_python
- Reconstruct FastAPI-compatible ValidationError structure to ensure complete backwards compatibility for error locations and input fields.

✨ Optimize response serialization using Pydantic v2 TypeAdapter
This commit introduces a fast-path for the jsonable_encoder and directly uses TypeAdapter(Any).dump_json() and dump_python() in astapi.routing and astapi.encoders. By leveraging the Rust-based pydantic-core directly, serialization overhead for complex types is significantly reduced.
- Use TypeAdapter(Any).dump_json() in _serialize_data and _serialize_sse_item
- Add fast-path to jsonable_encoder to use TypeAdapter(Any).dump_python(mode='json')
- Update test_sse_events_with_fields to account for minified JSON output of Pydantic v2

Optimize JSON parsing by using Pydantic V2 validate_json directly from request body bytes. - Add FastAPIOptimizedJsonBytes helper to mark bytes for optimized parsing. - Implement validate_json in ModelField to leverage pydantic-core's native JSON parsing. - Update get_request_handler to pass raw body bytes wrapped in FastAPIOptimizedJsonBytes when applicable. - Update _validate_value_with_model_field to use validate_json when receiving optimized bytes, avoiding redundant Python dict conversion.
