fix(models): coding runs on sonnet-5, judging on opus-5, haiku only as last resort

Operator model policy: haiku ONLY for genuine yes/no questions; anything requiring thinking is opus-5; coding is sonnet-5. The mission AGENTS were running haiku, and nothing in the product said so. `provider_alias_for` maps every `claude-*` binding onto the single alias `claude_cli.default`, so a crew whose `model_binding` reads `claude-sonnet-5` — as this deployment's does — still ran whatever that alias pointed at, which was `model = "haiku"` in the runtime config. The binding is cosmetic; the alias is the truth. Measured consequence on mission 01a00bbb: the coding agents claimed six INT items complete and had committed three, and the done_when judge caught it by auditing git history against the claims. Model assignments, by what the component actually does: evaluator (done_when judge) haiku -> opus-5 reads evidence, audits it against the repo, writes guidance. The verdict is a boolean; the work is not — and this is the one component whose failure mode is passing work that was never done. judge_model 4-8 -> opus-5 mission_refiner 4-8 -> opus-5 composition phase_summarizer 4-8 -> opus-5 composition swarm planner 4-8 -> opus-5 planning subscription preflight head 4-8 -> opus-5 fallback chain head 4-6 -> sonnet-5 haiku stays BELOW it as a last-resort link, never a peer Every value stays env-overridable; only the shipped defaults move.
