fix: expose exact lifecycle tool contracts

[veil-chow-fyaic]

Observed blocker

Fresh real Codex attempt 4 on main@e052299 completed five role bootstraps and registered the sole kickoff turn, then failed threadmesh_lifecycle_publication_action_mismatch before the first event-pump dispatch. The live model selected the kickoff tool without being given the exact coordinator-bound lifecycle arguments required by the existing fail-closed publication contract. Normal cleanup passed 5/5.

Bounded correction

• expose already-authorized lifecycle arguments through phase-specific dynamic-tool JSON Schemas;
• keep exact action/event/material binding unchanged;
• keep receiver decision choices constrained to the exact message;
• let verifier copy the current evidence revision/head from the preceding read-tool result rather than embedding dynamic state at bootstrap;
• retain the attempt in the canonical audit and status docs.

Evidence

• npm test: 379/379 tests, schemas/transitions/docs clean;
• focused exact-schema regression confirms kickoff/review fixed arguments and verifier dynamic head contract;
• deterministic full event-pump gate remains green.

Boundary

This does not add a protocol field, relax lifecycle authority, script a phase prompt, add an adapter, or claim a live chain pass. A fresh real run is still required.
