Meta and Attachment Shortcuts

Summary

This change adds high-level shortcuts for GitLink OpenAPI endpoints that were previously only reachable through Raw API:

• meta +licenses → GET /api/licenses.json
• meta +ignores → GET /api/ignores.json
• attachment +upload → POST /api/attachments.json
• attachment +delete → DELETE /api/attachments/{uuid}.json

User Value

• Maintainers can query license and .gitignore templates before creating repositories.
• Agents can upload files once, capture the returned attachment UUID/URL, and reuse it in Issue/PR/comment workflows.
• Destructive attachment deletion supports --dry-run to preview the request before remote mutation.

Validation

• Unit tests cover query parameters, multipart upload fields, dry-run behavior, missing local files, and deletion.
• README and Skill docs include command examples and Agent safety guidance.
