Specify the coverage file shape and wire Workflow A into Workflow D (I4, I5)

- I4: added a fourth Required Page Template for wiki/script-coverage.md
  spelling out the exact positional shape parseCoverageTable requires
  (metadata line syntax, column order, station spelling, lowercase all/yes) —
  Workflow D described the fields but never the shape, so a compliant write
  could still fail every parse. Also spelled out the seven station names in
  Workflow D step 3 and resolved the step 4 (pinned rows are protected) vs
  step 5 (stale rows are removed) ambiguity for a pinned row whose concept
  page is gone.
- I5: added Workflow A step 9, pointing any ingest that touches
  wiki/concepts/ at Workflow D before reporting — previously that trigger
  lived only inside Workflow D's own list, so an ingest run top to bottom
  never synced coverage and the right pane went stale silently.
- log.md: added "sync" to the intent docstring's valid values (Workflow D
  already required it) and corrected the 2026-07-28 entry's attribution —
  the concept grouping lives in index.md, not in script-coverage.md itself.
