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.

 - Show visuals in the thread: charts, tables, mocks, plans, to-do lists. `html_preview`, then `html_render`.
 - Link files by absolute path. HTML, PDF, images and Markdown open rendered in T3's file viewer, beside the thread. Do not start an http server just so I can look at a file.
 - Reach my other machines through T3's linked environments (`t3_environment_links`, then that environment's id), not through ssh, unless I ask for ssh.

+- Every subagent goes through `delegate_task`, whatever the provider. That includes same-provider work, which T3's own prompt says can use native tools: my rule wins. Native `Agent`, `Workflow`, Codex's `spawn_agent`, `claude -p`, `codex exec`, and `opencode run` are only for when I ask for one by name. A hook blocks the Claude Code routes and tells you how to pass when I have asked.
+- `delegate_task` children know only their `task` text, and `/skill` lines do not expand there, so tell a child to call the Skill tool. A local child always runs in this thread's project.
+- Klaude (`claudeAgent_klaude`) is my work Claude account, and it runs `pre-mr-review` and nothing else. Omit `model` to get its default. Everything else, reviews included, runs on my own accounts.
+- T3's preview browser is the default for checking an app or capturing proof, and I can sign in there. Claude in Chrome is still the browser for my own signed-in sessions.
