chore: fix biome check errors (40 → 0)

- Auto-fix: import sorting, formatting (17 files)
- Unsafe auto-fix: unused vars, template literals (7 files)
- Manual: nursery/noConsole → suspicious/noConsole suppression
- Manual: suppress noExcessiveCognitiveComplexity for cmdThreadResume and parseWorkflowPayload
- Manual: remove unused destructured vars in current-role tests

Closes #48
