KeiSei84 742822a499 feat: opt-in hook packs + stack profiles + public-prep repoint (#44)
Mirror of keigit main — Phase 2 (abae256c) + public-prep repoint (518d95df).

Phase 2: safety on by default, discipline packs opt-in; stack profiles
(minimal/web/ml/systems/mobile) pull packs + agent sets; SSoT in
_primitives/hook-packs.toml; filter+prune via lib-hooks.sh; re-runnable
via `kei configure`; 8 hooks gated via _lib/gate.sh.

Public-prep: .gitmodules + README clone + plugin homepage + web-install.sh
