fix(platform): unblock UI by deferring P2P mesh startup after session restore

platform.ready() no longer awaits Hyperswarm discovery/contacts or guild
mesh join before returning. Local identity and guild list restore in ~ms;
_finishSessionStartup() runs meshes in the background and emits session-ready.
