* chore(sprint-planning): convert workflow.yaml + instructions.md to unified workflow.md
Step 4 of 9 in the yaml-to-md conversion plan. Merges config
and instructions into a single self-contained workflow.md,
dropping engine scaffolding (critical tags, invoke-protocol).
* fix(sprint-planning): address review findings from PR triage
- Update stale workflow.yaml references to workflow.md in sm.agent.yaml and module-help.csv
- Widen epics_pattern from epic*.md to *epic*.md to match documented input files
- Fix placeholder mismatch: epics_in_progress_count → in_progress_count
