docs(dev): add pre-commit hook installation guide to contributor guides

[AdarshJ173]

Adds documentation for the local Git pre-commit hook installation to both English and Chinese contributor guides. Fixes #19

[samuel--hu]

Thanks for the contribution! The documentation content looks good for #19, and the English/Chinese updates are aligned.

I also verified the docs build locally with:

npm run docs:build

Before we merge, could you please clean up the commit history / DCO? The PR currently includes an extra merge commit:

Merge remote-tracking branch 'upstream/main' into docs/pre-commit-hook-installation

That merge commit is not signed off, while this repository requires DCO sign-off for commits. Please rebase your branch onto the latest main and force-push so the PR keeps a clean signed-off history, ideally just the documentation commit(s) with Signed-off-by:.

One small non-blocking doc suggestion: it would be helpful to add a short note that bash scripts/install-hooks.sh and rm .git/hooks/pre-commit should be run from a Bash environment such as Git Bash or WSL on Windows. Contributors who do not install the hook can still use the manual check commands you added.

Thanks again — this is a good scoped first contribution.

Reviewed against current main (1a1cab83).

The English and Chinese guides are aligned, and the documented install, uninstall, clang-format, and optional cppcheck commands match the current repository scripts.

Verification:

• Clean integration with current main
• npm run docs:verify — PASS
  • bilingual documentation/link checks passed
  • VitePress production build passed
  • rendered-page smoke tests passed (10 bilingual pages)

This PR will be squash-merged so the history-only unsigned merge commit is excluded while the contributor's existing Signed-off-by trailer is preserved.
