feat(ipc): control socket stage 2 - wake the render thread, brightness.set, plugin.reload (#720)

Browse Source 
Control socket stage 2: the render thread wakes for queued commands (static screens ~1 ms, Vegas within one frame), brightness.set, and plugin.reload after a store update, with mailbox/restart fallbacks. Rig checks listed in the PR body are still to run.
