feat(redis): add native JSON session storage for 4.1.0

- Add opt-in SESSION_REDIS_JSON storage for asyncio Redis backends. - Check JSON command support at startup and reject JSON mode on Trio. - Read legacy strings and migrate sessions on their next save. - Validate JSON objects before transactional replacement and expiry. - Preserve tagged serialization for datetime, tuple, and other types. - Cover command contracts, error handling, and session round-trips. - Document server requirements, permissions, and migration limits. - Normalize indentation and whitespace across code, tests, and examples. - Bump the package and lockfile to 4.1.0 and update the changelog. - Refresh the locked pycparser dependency to 3.12.
