* Tighten dependency bounds, remove stale overrides, restore Python 3.10 support

- Apply dependency bound policy across all packages: stable >=1.0 deps use
  >=floor,<next_major; pre-1.0/prerelease deps use validated hard-bounded ranges
- Remove stale root tool.uv.override-dependencies (uvicorn, websockets, grpcio)
- Lower github_copilot requires-python to >=3.10 with github-copilot-sdk gated
  behind python_version >= 3.11 marker; import raises ImportError on 3.10
- Skip github_copilot pyright/mypy/test tasks on Python <3.11
- Use version-conditional pyrightconfig for samples on Python 3.10
- Add compatibility fix in core responses client for older openai typed dicts
- Normalize uv.lock prerelease mode and refresh dev dependencies
- Update CODING_STANDARD.md, DEV_SETUP.md, and package management skill docs

Closes #902
