refactor: upgrade skills to Anthropic agent skills standard
Structure changes:
- Add metadata (requires.bins, cliHelp) to all SKILL.md frontmatter
- Add CRITICAL prerequisite notices for authentication/authorization
- Create references/ directory with per-shortcut reference files
(34 new reference files across 8 skills)
- Migrate examples/ to references/ (standard structure)
- Move REFERENCE.md and TROUBLESHOOTING.md into references/
New reference files:
- gitlink-issue: 6 refs (list, create, view, update, close, comment)
- gitlink-pr: 6 refs (list, create, view, merge, close, files)
- gitlink-repo: 9 refs (5 repo + 4 branch shortcuts)
- gitlink-release: 4 refs (list, create, view, delete)
- gitlink-org: 3 refs (list, info, members)
- gitlink-search: 2 refs (repos, users)
- gitlink-user: 2 refs (me, info)
- gitlink-shared: 2 refs (api-reference, troubleshooting)
Each reference follows lark-cli standard: prerequisites, commands,
parameters table, workflow steps, caution notices, cross-references.
