feat(rmk-types): replace rmk protocol module with rynk wire format
c5c2b8e 
Adds new rynk/ protocol module (buffer, cmd, header, fingerprint, mod)
with the new wire format. Migrates per-domain modules (combo, encoder,
fork, keymap, macro_data, morse, status, system) from the previous
rmk/ namespace, and removes the old endpoint/topic snapshot-based
layout. Also drops unused derives/imports across rmk-types/src/*.rs.
