resolveGitHooksDir now returns a directory only when it is the repo's own
<git-common-dir>/hooks (compared on canonical paths), so a core.hooksPath
elsewhere, global or repo-local, is never written to by postinstall, while a
core.hooksPath pointing back at the repo's own .git/hooks still resolves.
The pre-push hook skips with a one-line notice when a pushed ref is not the
checked-out HEAD (tags peeled) or when git status shows uncommitted or
untracked changes under a path the checks read (src, config, scripts, test,
package.json, package-lock.json, install.sh), since the checks read the
working tree rather than the pushed commit.
Also: honest timing (~10-40s instead of ~15s), CLAUDE.md Session Safety note
on CODEMAN_SKIP_PREPUSH for another session's WIP, 14 (not 9) Playwright
tests, and a note that the browser-excludes check only sees direct imports.
