Replace all GitHub API and gh CLI dependencies with Forgejo SDK via
pkg/forge. The bash dispatcher burned a week of credit in a day due to
bugs — the jobrunner now talks directly to Forgejo.
- Add forge client methods: CreateIssueComment, CloseIssue, MergePullRequest,
SetPRDraft, ListPRReviews, GetCombinedStatus, DismissReview
- Create ForgejoSource implementing JobSource (epic polling, checklist
parsing, commit status via combined status API)
- Rewrite all 5 handlers to accept *forge.Client instead of shelling out
- Replace ResolveThreadsHandler with DismissReviewsHandler (Forgejo has
no thread resolution API — dismiss stale REQUEST_CHANGES reviews instead)
- Delete pkg/jobrunner/github/ and handlers/exec.go entirely
- Update internal/core-ide/headless.go to wire Forgejo source and handlers
- All 33 tests pass with mock Forgejo HTTP servers
