fix(patches): silence retry noise, tighten h-entry check, fix stale comment

- retry: silently skip when livefetch:v2 marker is present instead of
  logging a misleading "target snippet not found (package updated?)"
  warning on every startup
- livefetch: match `h-entry"` or `h-entry ` instead of bare `h-entry`
  to avoid false positives from body text containing the string
- reset-stale: update comment to reference livefetch v2 (not retry)
  as the patch that prevents recurrence
