fix(diagnose): restore skill-root-relative script path

00c1e6b (the ADR-0020 retrofit of diagnose) moved a bullet referencing
scripts/hitl-loop.template.sh out of SKILL.md and into the new
references/feedback-loops.md, and in the move flipped the correct
skill-root-relative path into an incorrect parent-relative one
(../scripts/...) -- despite that commit's own message claiming to fix
"a script path that did not resolve." References in this skill are
written relative to the skill root regardless of which file carries
them, matching the convention used throughout SKILL.md.

Found via an independent post-closure audit of issue #99; validated
clean via skill-audit afterward.
