refactor: reduce cognitive complexity in 3 functions

Extract helpers to bring all functions below biome's complexity threshold (15):
- store/log-store.ts: extract recordToRoundMessage() from parseRoundPayload()
- cli/commands/workflow.ts: extract buildTruncatedSingleRound() from buildThreadCommandOutput()
- daemon/workflow-worker.ts: extract validateRoleResult(), buildInitialLastSignal(),
  initChain(), executeRole() from runThread()
