- Extract shared splitMessage() into channels/utils.ts (dedup 4 adapters) - Add Slack user name resolution with caching (users.info API) - Add withRetry() with exponential backoff + jitter, isRetryable() filter - Wire retry config into ModelRouter.chat() (non-streaming only) - Add assembleSystemPrompt() multi-file template system (SOUL/AGENTS/IDENTITY/USER/TOOLS.md) - Add usage tracking accumulators in NativeAgent + AgentOrchestrator - Add estimateCost() with per-model pricing table - Add /usage TUI command with full usage report formatting - Add retrySchema and promptSchema to config schema Tests: 569 passing, typecheck clean
