Give ack, builder, and deployer an explicit init/check mode that reports
missing project config instead of failing mid-work. Point builder at
makefile.builder so its contract targets do not collide with an existing
Makefile.
Keep pouch naming and .pouch/ack project state, and bring in ACK
regression mode, deployer test-environment binding, and manage-release
updates from main.
Use ~/.pouch, the pouch CLI, and .pouch.yaml as the SSOT container.
Keep the inner skills/ packages, and store ACK project state in
.pouch/ack instead of docs/ack.
ACK 0.19.0 hands test-environment deploys to the deployer skill,
documents bug-fix as a first-class scenario, and adds
docs/ack/regression.yaml harvest plus a /ack regression run.
