feat(scaffold): pre-commit runs webjs test + webjs check

Tool-agnostic git-level enforcement. Fires on every commit
regardless of agent (Claude, Cursor, Windsurf, Copilot, human).
Blocks commits that fail tests or convention checks.

Skipped on fresh clones before npm install (when the CLI is
not yet on PATH). To bypass in emergencies: git commit
--no-verify.
