K-ResDev 0.1.0 BETA 56

Beta 56 adds a read-only Admin Profile Pack Promotion Gate. It joins profile-review artifacts, hash-bound profile-promotion decisions, admin profile-pack structural review, and admin profile-pack human review receipts before any reviewed-seed mode is considered. It also integrates the gate with doctor, next-actions, workspace summary, review packs, trace, schemas, templates, and tests. Validation: python -m pytest; python -m compileall src; python quick_validate.py; python -m k_resdev_skill --version.
