Add role_namespace_gate to fail closed when reviewer-bound sessions attempt
author mutations (create_pr always blocked; create_issue only when profile
explicitly grants gitea.issue.create). Extend mutation audit records with
mcp_namespace, task_role, and operation fields. Add handoff parity checks in
review_proofs for author role vs reviewer namespace mismatches.

Extract TASK_CAPABILITY_MAP into task_capability_map.py as the single source
of truth shared by gitea_resolve_task_capability and issue-mutating tools.
Gate gitea_create_issue, gitea_close_issue, gitea_mark_issue, and
gitea_set_issue_labels with structured #142 permission reports. Add regression
tests proving resolver-denied tasks fail closed at the raw tool layer.
Implements mcp-control-plane #69.
