Expose issue_duplicate_context_fetcher on the MCP server so lock_issue,
commit_files, and create_pr duplicate rechecks avoid live Gitea calls in
unit tests. Update affected test suites to patch the fetcher without
weakening duplicate-work gate assertions.

Add commit_files and gitea_commit_files resolver entries for
gitea.repo.commit, align gitea_commit_files tool gates with other
issue-write mutations, and add regression tests for author allow,
reviewer deny, preflight order, and resolver/tool alignment.
