fix(entry-skills): every handoff arm says to invoke the skill

[leeovery]

Summary

• A prose-test walker on the bugfix path recorded a DEVIATION: the arm hands over a fenced block of arguments and never says what to do with it — no invocation directive, and no directive to emit it either. Reproduced identically on both independent walks, against the already-fixed fences, so it isn't a rendering artefact.
• Enumerating before fixing turned one arm into four, across three files:

file	arm
workflow-specification-entry	#### If work_type is bugfix
workflow-specification-entry	#### If work_type is cross-cutting
workflow-investigation-entry	#### If source is continue
workflow-planning-entry	#### If continuing or reviewing existing plan

• In every case a sibling arm in the same file carries the sentence and these don't. discussion-entry and research-entry carry it on every arm — the same proof structure that settled the fence bug: two files doing it correctly means the others are omissions, not house style.

Test plan

• Re-enumerated after the change: 13 arms across 8 files, 0 missing.
• Re-verified fence pairing afterwards, since these files were the subject of fix(entry-skills): close the handoff fences — six files render their arms wrong #550: 0 files broken.
• npm test green: 1699 tests, 0 fail.
• Diff is additions only — 8 lines, no wording altered.
