feat: gate reconciliation audit mode from unauthorized cleanup (Closes #419)

Add audit vs cleanup phase tracking so reconciliation audits stay read-only
unless cleanup is explicitly authorized with delete capability proof, safety
proof, and before/after snapshots. Block gitea_delete_branch and merged-cleanup
execution during audit phase, validate final reports for false no-mutations
claims, and document the boundary in the reconcile-landed-pr workflow.

+Audit/reconciliation tasks are read-only unless a separate cleanup phase is
+explicitly authorized with exact capability proof, safety proof, and
+before/after snapshots. Cleanup mutations must be classified in final reports;

+1. Operator approval or workflow authorization
+2. Exact ``delete_branch`` capability proof (``gitea.branch.delete``)
+3. Proof branch/worktree is safe to remove
+4. Before/after state snapshot
+
+Call ``gitea_authorize_reconciliation_cleanup_phase`` before any cleanup
+mutation. Final reports must not claim ``no mutations`` if cleanup occurred.
+Classify cleanup mutations as:
+
+* remote branch deletion → **External-state mutations**
+* local branch deletion → **Git ref mutations**
+* worktree removal → **Cleanup mutations**
+
+``audit_reconciliation_mode.assess_audit_reconciliation_report`` validates
+these boundaries in final reports.
+
 ## 16. Mutation classification
 
 Use precise mutation categories in the final report:

 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.
