feat(devops): 13 CLI-backed skills for forge, workspace, and diagnostics

Thin skill wrappers over core-agent CLI commands:
- workspace-list, workspace-clean
- issue-get, issue-list, issue-comment
- pr-get, pr-list, pr-merge
- repo-get, repo-list
- build-prompt, health-check

Each skill calls core-agent directly — no raw API calls,
no remembering flags. Edge cases fixed in the skill.
