feat: support Windows runner

[shenxianpeng]

Summary

Make this GitHub Action compatible with Windows runners (windows-latest). The core logic (main.py) is already cross-platform — the only blockers were in the composite action's shell run block.

Changes

action.yml

Before, all paths and commands were hardcoded for Linux/macOS:

Item	Linux/macOS (before)	Windows (broken)
Python command	python3	❌ python3 not available
venv activation	source venv/bin/activate	❌ should be venv/Scripts/activate
run main.py	python3 ...	❌ should use python

After this PR, platform-specific variables are set early:

if [[ "$RUNNER_OS" == "Windows" ]]; then
  PYTHON_CMD="python"
  VENV_ACTIVATE="venv/Scripts/activate"
else
  # Linux/macOS — unchanged behavior, DEB_PYTHON_INSTALL_LAYOUT still Linux-only
  PYTHON_CMD="python3"
  VENV_ACTIVATE="venv/bin/activate"
fi

All subsequent commands use $PYTHON_CMD and source "$VENV_ACTIVATE".

Compatibility

• ✅ ubuntu-latest — identical behavior (just indirect via variables now)
• ✅ macos-latest — identical behavior
• ✅ windows-latest — newly supported
• ⚠️ No changes to main.py — it already uses cross-platform stdlib APIs
• ⚠️ commit-check and PyGithub are both pure-Python wheels (py3-none-any), so no platform-specific wheel issues

Testing

Could you run the action on a Windows runner before merging to confirm? Something like:

commit-check:
  strategy:
    matrix:
      os: [ubuntu-latest, windows-latest]
  runs-on: ${{ matrix.os }}
  # ... rest of workflow

Summary by CodeRabbit

• Improvements
  • Enhanced cross-platform compatibility with OS-aware command execution for Windows and Linux environments.
  • Increased maximum commit message subject length from 80 to 100 characters for more descriptive commit messages.

Warning

Review limit reached

@shenxianpeng, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 16 minutes and 47 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

📝 Walkthrough

Walkthrough

action.yml is updated to detect RUNNER_OS and select the appropriate Python executable (PYTHON_CMD) and virtualenv activation path for Windows versus Linux, replacing hardcoded python3 references throughout the venv setup and main.py execution. commit-check.toml increases subject_max_length from 80 to 100.

Changes

Cross-platform action script and config update

Layer / File(s)	Summary
OS-aware Python venv setup and execution action.yml	Adds a platform detection block that sets PYTHON_CMD and the venv activation command based on RUNNER_OS (Windows vs. Linux), applies a Debian install layout tweak on Linux only, and replaces hardcoded python3 with $PYTHON_CMD for dependency installation and main.py execution.
Commit subject max length increase commit-check.toml	subject_max_length in the [commit] section is raised from 80 to 100.
