feat: add markdown-validator agent and scoped-labels skill
- Add markdown-validator agent for validating Gitea issue descriptions
- Add scoped-labels skill for managing exclusive labels (status::, priority::, type::)
- Add init-scoped-labels.sh script to create standard label sets
- Add GiteaClient methods: createLabel, updateLabel, setScopedLabel, setScopedStatus, setScopedPriority
- Support exclusive labels (scoped labels) in Gitea API 1.21+
Created scoped labels:
- status::new, status::planned, status::in-progress, status::review, status::testing, status::done, status::blocked, status::cancelled
- priority::critical, priority::high, priority::medium, priority::low
- type::bug, type::feature, type::enhancement, type::documentation, type::refactor, type::test, type::chore
- size::xs, size::s, size::m, size::l, size::xl
Scoped labels are mutually exclusive within their scope - applying status::in-progress automatically removes status::new
