fs.mkdirSync(dir, { recursive: true }) is a no-op on an existing directory
in Node, but bun on Windows throws EEXIST - crashing hook install on any
repo whose .git/hooks already existed, leaving the repo unprotected.
Add lib/fs-utils.ts mkdirpSync: swallow EEXIST only when statSync confirms
the path is an existing directory; a regular file occupying the path, a
stat failure, or any other errno still rethrows. Use it in
installPrepushHook().
The regression test emulates the Windows bun fs semantics via a
bun --preload fixture, so the exact crash path runs (and fails on the old
code) on any platform, including CI Linux.
Absorbed from PR #2641 with authorship preserved.
Fixes #2635
