waning-sun/dsh-session-wake

Wakes a DSH conversation on demand and hands work to it: pick one or more sessions to auto-wake when DSH starts, give each session its own provider, model and reasoning effort, and let the agent call another conversation with the session_task tool — it wakes that session, delivers the content, waits for it to finish and brings the answer back. Also ships list_sessions and wake_session tools plus a settings page titled; no QQ or bridge dependency. The three tools are available to every agent and can reach any session in the profile; the auto-wake list is empty by default, a session's boot prompt is delivered at every DSH start, and session_task waits up to 300 seconds by default.
