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).
Document resetQuestIds, resource-node fixture, and cooldown clear in server README; add TryClearProgress Postgres integration test; sync-review doc and Bruno require paths.
Extend quest and resource-node fixture APIs so Bruno pre-requests can reset shared dev-local-1 state (cooldowns, nodes, inventory, quest progress) instead of relying on a fresh Postgres baseline.
