<#
.SYNOPSIS
  Rotate context/context_packets/*.json and context/briefs/*.md into history/YYYY/MM/<workflow>/.

.DESCRIPTION
  v0 utility script. Manually run to move files older than a threshold (default 7 days).
  TODOs:
    - Infer workflow from filename/path instead of defaulting to "ticket_triage".
    - Hook into a scheduler (Task Scheduler / cron) when automation is ready.
    - Add dry-run / log output as needed.
