feat(skills): shared authoring standards make learned skills routable (#115103)

* feat(skills): share authoring standards * fix(skills): derive routable autocapture proposals * docs(skills): document proposal authoring standards * refactor(skills): simplify autocapture derivation * fix(skills): preserve explicit reflection rules * docs(skills): state the accepted heuristic-detection tradeoff * fix(skills): preserve explicit directive syntax * style(skills): keep signal parser within ratchets

   a stable procedure that would remove at least two future model or tool round
   trips.

+Generated proposals follow shared authoring standards: class-level names,
+one-sentence descriptions that lead with the task or trigger, and compact
+evidence-backed imperative steps. They retain supported pitfalls and
+verification checks, capture working fixes, and do not invent commands, paths,
+flags, or APIs.

 Good candidates include:
