chore: remove duplicated archy skills and redundant hooks

Wrong archy-specific skills (harden, refactor, test, ux-review, lint,
add-app, pwa-icon-cache-fix) removed — these referenced Archipelago
infrastructure irrelevant to botfights. Redundant hooks (block-risky-bash,
protect-files, post-deploy-check, post-push-progress) removed since global
hooks provide superset protection.
