Subject: [PATCH] feat(nix): add flake checks for CI validation

Consolidate all CI checks into nix flake check for unified validation:

- formatting: treefmt check (nixfmt, ruff-check, ruff-format, oxfmt)
- gitleaks: secret detection
- uv-lock: verify lockfile is up to date
- ty: type checking with Python 3.13
- pytest: test suite execution

All checks use --locked flag to ensure lockfile consistency and pin
Python to 3.13 for compatibility with dependencies like onnxruntime.
