feat: gate author work on early duplicate-work detection (Closes #400)

Add author_duplicate_work_gate and enforce it at claim, lock, and PR creation. Expose gitea_assess_author_duplicate_work for pre-commit/push checks and extend work-issue final-report verification. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>

 Before claiming or working on an issue, check whether there is already an open PR, branch, or active claim for that issue.

+Run `gitea_assess_author_duplicate_work` at these stages and stop when `block` is true:
+
+* `claim` — before `gitea_mark_issue`
+* `lock` — before `gitea_lock_issue`
+* `worktree` / `edit` — before creating a worktree or editing files
+* `commit` — immediately before `git commit`
+* `push` — immediately before `git push`
+* `create_pr` — immediately before `gitea_create_pr` (also enforced server-side)
+
+`gitea_mark_issue`, `gitea_lock_issue`, and `gitea_create_pr` enforce the same gate server-side and fail closed.
+
+If a concurrent open PR appears after work begins:
+
+* before commit or push — stop and preserve local work without pushing
+* after push but before PR creation — produce a reconciliation handoff instead of opening a PR
+
+Final reports must name the duplicate-work outcome (`duplicate PR prevented`, `duplicate branch prevented`, `duplicate commit prevented`, `duplicate push prevented`, `duplicate work not prevented`, or `reconciliation handoff`).
+
 If an open PR already exists for the issue, do not implement duplicate work.
