feat(agent-queue): build/ship lifecycle with auto-QA verify gate + manual ship
Redesign the kanban runner stages from inbox->doing->done/failed to
inbox->building->review->testing->shipped (+ failed):
- worker: agent rc=0 lands in review/, then runs the configurable
verify command (frontmatter verify: / AGENT_QUEUE_VERIFY) in cwd;
pass -> testing/ (QA), fail -> failed/, none -> parks in review/
- new commands: ship (testing->shipped, manual gate), promote
(advance one stage), reject (review/testing->failed); requeue now
also pulls from review/testing
- status + dashboard.mjs render all six stages; RECENT panel labels
shipped/testing/review/verify_failed/timeout/rejected
- README: new lifecycle diagram, verify: frontmatter, result= glossary,
command table + folder layout
- selftest: assert no-verify->review, verify-pass->testing->ship->shipped,
verify-fail->failed
- rename queue/doing->building, queue/done->review; add testing/ shipped/
