Windows Testing and Support

[LeeSinLiang]

Windows testing & support (hooks + docs + CI)

Summary
Ensure CommitLM works smoothly on Windows (PowerShell/CMD), including hook installation/execution, CRLF handling, and quick-start docs. Add a minimal Windows CI smoke test.

Motivation
Reducing setup friction in Windows increases adoption and contribution success.

Scope

• Detect Windows during commitlm install-hook and install PowerShell/CMD-friendly hooks (shebang/exec bit considerations, CRLF-safe wrappers).
• Add README “Windows setup” block (PowerShell policy note, venv activation, sample workflow).
• Add GitHub Actions job (windows-latest) that runs a smoke test: init a temp repo, install hooks, create a dummy change, run git commit, confirm docs file created.

Out of scope
WSL-specific optimizations.

Tasks

• Update hook installer to generate .ps1 / .cmd wrappers on Windows.
• Normalize line endings and document git config core.autocrlf recommendations.
• Add README Windows section with exact commands.
• Add windows job to CI with the smoke test above.

Acceptance criteria

• Hooks install and run successfully on Win 11 + Git for Windows (CI proves it).
• README contains a concise Windows quick-start.
• No crash when default shell is PowerShell or CMD.

Test plan

1. commitlm init && commitlm install-hook on Windows.
2. echo "x" > demo.txt && git add . && git commit -m "chore: test" → docs file appears under docs/.
