feat: Drop Python 3.9 support for v1.5.0

[shenxianpeng]

Summary

• Drop Python 3.9 support and set the package minimum to Python 3.10.
• Raise vulnerable dependency floors for pip and pytest, then refresh uv.lock so Dependabot security alerts resolve to patched versions.
• Update README and example pre-commit snippets to reference the planned v1.5.0 release.

Impact

cpp-linter-hooks v1.5.0 will require Python 3.10 or newer. This allows the lockfile to avoid vulnerable Python 3.9-compatible dependency branches for pip, pytest, and filelock.

Validation

• uv run pytest -> 113 passed in 39.29s

Summary by CodeRabbit

• Documentation

  • Updated all examples and documentation to reflect version 1.5.0.

• Chores

  • Increased minimum Python version requirement to 3.10.

Footnotes

1. 13 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (31a75ea) during the generation of this report, so fab85d9 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩
