🤖 Apply lean Athanor review fixes

Adept dispatches no longer pass a model alias over the pin. Igor checks
the stamped model id of plan, attack and phase-review outputs before
acting on them. Implementation work no longer goes to the Athanor as an
unplanned brief. The spawning reference says plainly that "verified"
means read from the schema, marks fork availability unverified, and
cites the 184/184 evidence for alias-over-pin. Minor consistency fixes:
trunk notes, re-check failure path, staging, fallout diffs, run-log
timing.

 Short, for the next agent that has not read the code: key files and seams, invariants the phase touches, every consumer of a changed semantic, the gate command, known traps. A page, not a design document.
