Live github (issue-comment poster) and claude_code (file-drop) transports, plus GithubIntake (labeled issue -> coordinator.start_task, de-duped). run-team _build_transport now wires github/claude_code live (was SystemExit) + adds the intake-github subcommand. claude_code drop-path also neutralizes backslash (defense-in-depth).
slack_live: real slack_sdk poster. slack_listener: Socket Mode inbound; trust boundary = app-token auth + an explicit owner allowlist on the sender (fail-closed, rejects all if AGENT_TEAM_SLACK_OWNER_IDS unset) + the open-status CAS as anti-replay. Closes the AUTHZ-01 missing-sender-authz finding from the security review.
