feat(harness): meta-harness and PM launching off T3 (#1523, row 41)

Slice 1 S6. packages/harness runs a role session under the pi or claude adapter behind a tool gate, and packages/seat holds the session and its process. The bus host gains a launch socket: `mosaic bus start <business> --pm <harness>:<model>` runs the PM without a window, the PM launches role sessions through the broker within the business file's `launch.max`, and every launch, refusal and end is a launch-log line and a broker event. `mosaic talk`, `mosaic launches off|on|list` and `mosaic stop <run>` are new CLI verbs. packages/bus gains the IPC ops identity, authorize, refuse, endLaunch and credentialStatus, plus Broker.endLaunch (decision 77); no socket verb, event kind or schema changed. The session environment is an allowlist, and the runner exits before claiming if a founder credential reaches it. Filbert built it (agents/filbert/work/s6). Darkwing reviewed on #1523: round 1 changes (26991/26995), round 2 changes (27004/27010), round 3 changes (27012/27032), round 4 approve (27033/27034) on manifest 08a78972, 42 paths. Sage's gate on 64b0f9f1 (12:32Z), sequential and teed: node suites business 60, bus 74, cli 83, control-board 124, conversation 182, discord 178, harness 56, ledger 78, mosaic 69, queue 149, runs 41, seat 27, tasks 51, webui 39, every one 0 failed; test-auth 15, test-conductor 17, test-config 24, test-discord 66, test-extension-package 18, test-foundation 44, test-queue 27, test-release 14, test-task 98 and 26 without Docker, all 0 failed. 64b0f9f1..ee7f909b touches none of the 42 paths. It landed after the Q14 hold ended at 2026-10-11T17:19:23.857Z. The recorded PM-to-coder run on a scratch data root is still owed before row 41 moves to done.
