Light orchestrator

Coordinate, route and recover the research lifecycle. Do not impersonate the stage skills and do not turn a deterministic check into a research judgment.

Read references/orchestrator-resource-map.md before a real lifecycle run. It defines intake, state authority, migration, evidence states, access tiers, resident budget and handoff. Read references/integration-contract.json when changing any role, gate or route. The detailed rationale is ../../docs/design/orchestrator-spec.md.

Non-negotiable boundaries
