When the repo is checked out as a nested worktree, a go.work in the
outer tree hijacks module resolution, which makes the rebuild fails
with "main module does not contain package." Set GOWORK=off for the
build since the hook is self-contained.
Bumps HOOK_VERSION so existing installs pick up the fix.

Pull the hook logic into a reusable githook library package so
tailscale/corp can share it via a thin wrapper main instead of
keeping a forked copy in sync.
The install flow also changes: a wrapper scripts now build the
binary and reinstall the git hooks. Pulling new shared code no
longer requires re-running the installer.

Add misc/install-git-hooks.go and misc/git_hook/ to the OSS repo,
adapted from the corp repo. The primary motivation is Change-Id
generation in commit messages, which provides a persistent identifier
for a change across cherry-picks between branches.
The installer uses "git rev-parse --git-common-dir" instead of go-git
to find the hooks directory, avoiding a new direct dependency while
still supporting worktrees.
Hooks included:
- commit-msg: adds Change-Id trailer
- pre-commit: blocks NOCOMMIT / DO NOT SUBMIT markers
- pre-push: blocks local-directory replace directives in go.mod
- post-checkout: warns when the hook binary is outdated
Also update docs/commit-messages.md to reflect that Change-Id is no
longer optional in the OSS repo.
