tasks, bus, harness, seat: the approved requirement ids as data (#1584)

Row 90, round 2. Dewey built it, Filbert approved it (comment 28068) on
manifest 95611274 (21 paths, base b8539480). The approved PRD's
requirement ids live in packages/tasks/requirements.json. task_create
refuses an id outside it, and the PM session gets a list_requirements
tool. Round 2 adds requirements.mjs to the sandbox's RUNNER_FILES
(decision 127). Sage gate on c047d028 plus the patch, 23:50:16Z to
23:54:26Z: tasks 89, bus 111, harness 66, webui 101, cli 123, seat 33,
business 60, control-board 124, queue 150, conversation 182, discord 178,
ledger 78, runs 43, mosaic 69, all fail 0. Every scripts/test-*.sh
exited 0.
