CONFIGURED - Auto-activate git hooks via npm prepare script

Add a prepare script that runs 'git config core.hooksPath .githooks' on every
npm install, so the commit-msg style gate and pre-push test gate turn on
automatically per clone with nothing to remember. Guarded with '|| true' so
installs never fail where git is absent (e.g. tarball deploys). Document that
the deploy server never needs it since it only pulls.
