feat: ✨ add OpenSpec change for org-level label support (#125)
Adds the spec-driven change artifacts for exposing Forgejo
organization labels through the MCP server:
- proposal: motivation, capabilities, impact
- design: decisions, trade-offs, impl approach via DoJSONList
- specs: new list_org_labels capability + modified list_repo_labels
with include_org_labels merge and scope tagging
- tasks: 5-group breakdown covering helper, new tool, augmentation,
docs, and verification
Tracked as forgejo-mcp-7ch (blocked by forgejo-mcp-xv0 OpenSpec).
Closes forgejo-mcp-xv0.
