Summary

PyPI does not allow the project name ccache ("This project name isn't allowed" when adding a pending publisher), so the v4.14.2 upload to PyPI failed. This PR renames the PyPI package to ccache-bin, following packages such as nodejs-bin and gh-bin. The wheels and the installed ccache command do not change.

• pyproject.toml: name = "ccache-bin". The wheel files are now ccache_bin-<version>-py3-none-<platform>.whl.
• README: install with pip install ccache-bin / uv tool install ccache-bin. It also explains why the name isn't ccache and shows the uvx --from ccache-bin ccache form. The PyPI badge and links are updated.
• Workflows: the install tests, the uv resolution check, the PyPI/TestPyPI environment URLs and the Release Drafter header all use ccache-bin.

Checked locally:

• All 6 wheels build and pass twine check --strict.
• uv resolves ccache-bin==4.14.2 for all 8 targets.
• pip install ccache-bin passes the smoke test, and uv tool install ccache-bin provides ccache.

Before the release

• Pending trusted publishers for project ccache-bin on PyPI (environment pypi) and TestPyPI (environment testpypi). Owner cpp-linter, repository ccache-wheel, workflow publish.yml.
• The existing v4.14.2 release and tag were built with the old name. Delete both, then publish the v4.14.2 draft that Release Drafter recreates.
