- ship/SKILL.md: Add Edit, Write to allowed-tools so Phase 5 "Fix
  Selected Items" can actually modify files
- pr-review/SKILL.md: Fix broken grep invocation where glob patterns
  after -- were treated as filenames instead of filtering stdin
- README.md: Add `text` language tag to 3 unlabelled fenced code blocks
  (markdownlint MD040)
