Fix samples(n) regression; add ruff + ty checks

[events555]

Summary

Introduced type-checking (ty) and a linter (ruff) to catch errors during CI. There was a regression with the _samples_dict() call where time_column and title_row were being passed but unhandled.

Fixed

• _SamplesDict.__call__ no longer forwards time_column/title_row to _samples_dict (5e202dc)
• Tightened RPC type handling: None type in _Rpc.__repr__, _RpcAction returns None, reply-type asserts in _call (8a55bb3)
• Linux wheel builds (install libudev), ty dependency resolution (ipython), and Node 24 action bumps (cd63c0f)

Added

• Type stub for the _twinleaf Rust extension module (5157364)
• CI job running ruff + ty (3c243da)

Changed

• Configured ruff and ty in pyproject.toml (dbb9ddd)
• Cleaned up example imports (dcc790e)
• Formatted with ruff format (284dd9e)
• Build wheels only for x86_64/aarch64 (glibc & musl), aarch64 on native ARM runners; quiet uv cache warning (5c48509)

Release

• Bumped version 0.2.2 -> 0.2.3 (9e6861e)
