Add a project-scoped spawn_session tool so agents can dispatch new, independent sessions (ralph loops, long-plan chaining). Spawned sessions are constrained to a workspace/worktree of the same registered project, appear in the session list immediately via a new session.created event, and the capability is on by default with a Settings -> Session daemon toggle (spawnSessions / PI_WEB_SPAWN_SESSIONS). Note: adds a session daemon code path, so pi-web-sessiond.service must be restarted manually for the server side to take effect.
