Commit Message

:zap: Optimize handler hot-path performance (#1443)

- Reorder event routing: HTTP v2/v1 checked first instead of last
- Replace inspect.getfullargspec with try/except TypeError fallback
- Cache ApacheNCSA formatters as module-level constants
- Use time.perf_counter() instead of datetime.now() for timing
- Cache text mimetypes tuple on instance during __init__
- Eliminate double merge_headers call in v1 HTTP path
- Build minimal ASGI log environ with only required keys
- Use _LogResponse namedtuple instead of mutating werkzeug Response
- Title-case headers in payload processors to avoid extra dict copy
- Lazy-import boto3 in _get_boto_session (cold-start only)
