Add a new `dispatch-idle-formulas` step between `file-at-constraints` and
`journal-and-memory`. This step scans available formulas, checks for stale
or missing data, and files action issues to dispatch idle formulas.
Key changes:
- New step runs after constraint filing, independent of the 3-issue budget
- Excludes nervous-system formulas (AD-001: cron, not action issues)
- Checks open action issues, recently closed issues, and evidence timestamps
to determine staleness (7-day window)
- Journal format updated to log dispatched idle formulas
