The "files" field in package.json listed "hooks/dist" instead of "hooks",
which excluded gsd-session-state.sh, gsd-validate-commit.sh, and
gsd-phase-boundary.sh from the npm tarball. Any fresh install from the
registry produced broken shell hook registrations.
Fix: replace "hooks/dist" with "hooks" so the full hooks/ directory is
bundled, covering both the compiled .js files (in hooks/dist/) and the
.sh source hooks at the top of hooks/.
Adds regression test in tests/package-manifest.test.cjs.
