Remove clang-format and clang-tidy as dependencies

[Copilot]

Having clang-format and clang-tidy pinned as install-time dependencies means they land in the venv unconditionally. When a user provides a wrong path to clang tools, the system silently falls back to these pre-installed versions rather than failing visibly.

Changes

• pyproject.toml: Removed clang-format and clang-tidy from dependencies. Tools are still installed on-demand at runtime via the existing resolve_install → _install_tool (pip) mechanism.
• util.py: DEFAULT_CLANG_FORMAT_VERSION and DEFAULT_CLANG_TIDY_VERSION now derive from the tail of the auto-updated CLANG_FORMAT_VERSIONS/CLANG_TIDY_VERSIONS lists in versions.py, instead of being read from pyproject.toml dependencies.
• uv.lock: Regenerated; removes clang-format, clang-tidy, and the transitively pulled setuptools.
• .github/workflows/release-drafter.yml: Removed the Set up Python and Install dependencies steps. Version extraction now reads directly from versions.py via sys.path, eliminating the need to install the package at all.

Done in 304561b. Removed the Set up Python and Install dependencies steps entirely — the version extraction step now reads directly from versions.py using python3 -c "import sys; sys.path.insert(0, 'cpp_linter_hooks'); from versions import CLANG_FORMAT_VERSIONS; print(CLANG_FORMAT_VERSIONS[-1])" without needing the package installed.
