Apply Roslyn/dotnet-format fixes across NeonSprawl.Server and
NeonSprawl.Server.Tests: collection expressions, concrete helper
return types, record XML docs, logging guards, quest store refactors,
and removal of redundant usings via GlobalUsings.cs. Extend
csharp-style.md with the recurring patterns.
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).
Replace .ToArray() with collection spread, simplify single-statement
await using blocks, use Lock for Postgres schema gates, and document
IDE0063/IDE0305/IDE0330/CA1859 conventions in csharp-style.md.
Apply completionRewardBundle.reputationGrants via ReputationOperations with
compensating rollback; thread faction stores through quest wiring; add operator
chain Bruno helper and grid-contract accept success; update README and E7.M3 docs.
Evaluate FactionGateRule rows before TryActivate; deny with faction_gate_blocked
when standing is below minStanding. Integration and Bruno deny smoke included.
