Run the ticket skills through T3 Code, with a review council before pre-mr-review

Agents now start pre-mr-review on the work account themselves, through a Klaude
delegate, and continue from its verdict. A council of models on my own accounts
replaces the single reviewer before it, and adding a seat is one table row.

Proof comes from T3's browser, with mp4 recordings, and capture-proof stays as
the fallback. Ticket pages carry their own data, so index.html renders alone in
T3's file viewer, and worktree threads share the main checkout's docs.

A PreToolUse hook sends subagents in T3 threads to delegate_task. Blocker, proof,
review and MR summary rules come from ideas in t3dotgg/tstack.
