nit(#141): fix stale-docs error message phrasing

"ERROR: stale docmap docs: entries" had a vestigial "docs:" fragment
that reads awkwardly (looks like a YAML reference).

Change to: "ERROR: stale docmap entries (paths do not exist):"

Addresses NIT finding in review #4175.

-- **NEVER act on a PR with active REQUEST_CHANGES.** Fix the findings first.

-The first two constraints are statically enforced by `check-invariants.sh`: S1 and S9 cover the dispatch script (no merge, no close); S8 covers worker templates (no merge calls); S10 covers worker templates (no close calls, with NEVER-close text verified present in each). The remaining two constraints (token usage and REQUEST_CHANGES gate) are enforced by runtime logic.
