* fix(checklist): clarify file handling behavior for append vs create
Resolves contradictory instructions in checklist.md lines 97-99 where the
template stated both 'append to existing file' and 'creates a NEW file'.
Changes:
- Clarified that if file doesn't exist, create new with CHK001
- If file exists, append new items continuing from last CHK ID
- Emphasized preservation of existing content (never delete/replace)
