Re-vendor the murderboard to 81a0927: the stale copy had nothing to say about cost

[syncytium2]

The freshness gate refused a review, correctly. bugarach sat at 3a6a8fb; upstream is 81a0927, and the difference is not cosmetic.

Upstream added a cost section after a run on 2026-09-07 spent a two-day usage limit under a model that could not finish and produced no review at all. That is the shape of the failure: you do not get a partial review for a partial price, you get no review and the full bill.

What the stale copy was missing, in its own terms:

• the process is a fan-out — what scales to stakes is how the roles are run, never which ones, so there is no cheap murderboard;
• do not start a run on a model you cannot afford to exhaust (Opus 5 named as known good);
• ask the human before every run, because the other way this wastes money is firing early at a draft that was not ready;
• if blocked or declined, stop — never economise by running fewer roles, because "a review missing roles is indistinguishable in the report from a clean one."

That last clause is what this repo would otherwise have violated silently, which is what a freshness gate is for.

What was and was not touched

Re-copied with tools/murderboard_revendor.py, which is surgical about stamps for reasons documented in its own header. The three locally adapted tools were not rewritten: none changed upstream between the two commits, so the body difference the tool reports is bugarach's own # instrument: line on line 3 — verified still present in all three. The eleven compiled agent files already agree with the new process file.

Landed on main, not on the branch that wanted it. A vendored copy on a feature branch leaves every new worktree inheriting the old one; the skill warns about this in terms.

Not adopted, deliberately

Upstream also ships murderboard_model_gate.sh — a PreToolUse hook that reads the running model and blocks the call-up before the fan-out starts — and TERMS.md. bugarach vendors neither. The gate is the mechanized half of everything above, and wiring it deserves to be a decision rather than a side effect of a re-vendor.
