Remove uv workspace and lockfile

The CI uses uv pip install (not uv sync), so the workspace root
pyproject.toml and uv.lock provided no practical value. Remove them
along with workspace-only artifacts:

- Root pyproject.toml (workspace definition, cross-package conflicts)
- uv.lock and its .gitattributes / .pre-commit-config.yaml exclusions
- { workspace = true } source mappings in cuda_core and cuda_bindings
- cuda-pathfinder from cuda_core build-system.requires (was only needed
  for the workspace resolver)

Per-package [tool.uv] conflicts (e.g. cu12 vs cu13 extras) are retained
in their respective pyproject.toml files.
