feat: register work-issue task routing for role-aware MCP (#139)

- Map work_issue/work-issue to author role and gitea.pr.create in resolver
- Route work-issue sessions through role_session_router before mutations
- Expose work_issue in runtime context task capabilities
- Add work-issue workflow source verifier and canonical routing docs
- Tests for resolver, router, and final-report verifier

Closes #139
