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.

Add server-side duplicate detection in gitea_create_issue that re-queries
open and recently closed issues at mutation time, blocks normalized title
matches unless the operator explicitly approves a split, and validates LLM
duplicate-search summaries via review_proofs.
