chore(scribe): Mandate ### YYYY-MM-DD: format in Scribe charter

[diberry]

Problem

The Scribe charter says 'merge inbox into decisions.md' but never mandates ### YYYY-MM-DD: format. Early decisions have no dates, causing archival bugs. The daysAgoFromLine() parser assumes dates exist but the format was never enforced.

From

Postmortem action item A4, Procedures review of #20.

Proposed Fix

1. Update Scribe charter template (.squad/templates/scribe-charter.md) to mandate: 'All merged entries MUST use ### YYYY-MM-DD: Topic format. Add date if missing from inbox file.'
2. Update squad.agent.md Scribe spawn template with format validation step
3. Consider: should Scribe reject malformed inbox entries or auto-fix them?
