[deep-report] Introduce token guardrails for Smoke Codex high-usage runs

[github-actions]

Description

Daily audit and weekly CI/CD health reports show Codex workflows (notably Smoke Codex) consuming outsized tokens (24.5M in a single run, ~12M average for Codex). Add a token budget or prompt-size guardrail to prevent runaway usage and surface early warnings.

Expected Impact

Reduced cost volatility and more predictable runtimes for Codex workflows during release mode.

Suggested Agent

Cost-optimization agent or workflow performance agent

Estimated Effort

Medium (1-4 hours)
