Add xorg module plan and audio forward-compatibility note

Browse Source 
xorg module: XRandR geometry queries, screen grab source (XShmGetImage),
frame viewer sink (XShmPutImage, fullscreen per monitor). All exposed as
standard source/sink node roles on the existing transport.

Audio: deferred but transport is already compatible — channel_id mux,
audio_frame message type slot reserved, relay/allocator are payload-agnostic.

Also marks serial as done in planning.md.
