fix(config): check correct path to prevent re-prompting about pre-hooks (#765)

The `isFirstHooksRun` check looked for `.vite-hooks/pre-commit` (user-defined
hook) but `install()` only creates `.vite-hooks/_/pre-commit` (internal shim).
This caused `vp config` to re-prompt about hooks on every run.
