docs(plan/145): fix step order and link style in review note (round-3 xhigh)

Round-3 code review (xhigh) found one confirmed factual error and one
style issue in the review note:

1. The mise-registry soft-skip description had ::warning:: and
   skipped=true in the wrong order. Actual release.yml (lines 830-832)
   emits ::warning:: first, then sets skipped=true in $GITHUB_OUTPUT,
   then exits 0. Corrected the sequence.

2. The releasesmoke.go Markdown link had backtick-only link text
   ([`path`](url)), which is unusual. Switched to a prose-symbol label
   ([`RequiredSmokeChannels`](...)) matching the project's link style.

Skipped two candidates as false positives:
- "No checkbox updates": all in-repo tasks were already checked off;
  external-registry items cannot be closed until registries accept.
- "Vague 'carry' in last bullet": the registry-status content lives in
  body prose, not a named frontmatter field — there is no field to cite.
