Item 75: document ring-buffer analysis and unsolved sizing problem

Expand the msgqueue memory amplification item with detailed analysis
of the ring-buffer replacement approach and the fundamental sizing
problem (0-byte messages bypass window accounting).

Modified Files:
src/ssh/TODO.md
Log Message:
Consolidate TODO items 67, 75, 95 into 101 (channel I/O redesign)

Item 67 (setup mailbox blocks demux): resolved by dssh_chan_accept()
running on app's thread. Demux queues, never blocks on callbacks.

Item 75 (msgqueue per-message malloc): resolved by eliminating the
message queue entirely. ZC: callback into rx_packet. Stream: ring
buffers. initial_window=0 bounds the 0-byte message flood.

Item 95 (unify channel I/O API): subsumed by the full redesign in design-channel-io-api.md.

All three are now part of item 101 with cross-references.
