Under the hood

Remote-session connection driving gains a dedicated commands path for session control.
Config and API surface continues to expand around Guardian v2 settings (including transcript options), external-agent detection/migration, managed hooks requirements, marketplace metadata, skills config writes, thread metadata updates, and related exec-approval responses.
Dependency set picks up event-listener-strategy as part of async/listener infrastructure.
