Add ContractCompletionOperations orchestrator (deliver-then-mark,
outcome audit), hook from EncounterCompletionOperations after E5.M3
loot and quest wiring, extend dev fixture reset for contract rows,
Bruno quest-fixture reset request, and cover with tests (904 green).
Durable per-player contract instances (one active) and append-only
outcome audit rows, mirroring NEO-116/135 store patterns with V011/V012
migrations, AAA tests, README docs, and Bruno health smoke.
