Garry TanandOpenAI Codex eb4fd65ed3 fix: use agent capture budgets for deploy evals
Multi-turn deploy and benchmark sessions were incorrectly limited to the single-call judge timeout. Use the existing capture tier and leave outer-test cleanup headroom, with a free policy regression test. Keep all behavioral assertions and frontier models unchanged.

/**
* Two invariants over paid-test timeout policy:
*
* 1. FIT: every tier in test/helpers/eval-budgets.ts executes inside the
* sharded runner's wall with real overhead (bun startup + module load +
* reporting). A budget the wall kills first is fiction — the failure
* surfaces as a shard 'timed-out' (no bun summary, no per-test message)
* instead of a clean test timeout. This is the structural fix for the
* seven 1,700s-inside-a-1,500s-job literals found in the 2026-08 audit.
*
* 2. RATCHET: raw numeric timeout literals in paid test files only shrink.
* New tests use the tiers; a literal is legal only with justification,
* and the count is pinned so sprawl can't regrow.
