feat(KB-097): clean up type errors and remove obsolete code

- Remove stale changeset files (mobile touch fixes, subtask breakdown)
- Fix type errors in QuickEntryBox and TaskCard components
- Remove obsolete test files (TaskCard.test.tsx, triage.test.ts)
- Fix import issues in planning.ts
- Clean up triage.ts and useAgentLogs.ts
