feat(tymux): receive CWD in native client; bump proxy type cap
The native client (termtymux) now stashes the daemon's CWD broadcast
in a new Eina_Stringshare *last_cwd field; empty/oversized payloads
clear it, while malloc failures preserve the stale value. The field
is cleaned up in termtymux_free. The CLI proxy bumps its receive-cap
from > 11 to > 14 to accept CWD (14) and incidentally fixes the
already-armed PAUSE (12) and RESUME (13) handlers that were being
silently rejected by the too-tight cap. No user-visible behaviour
yet — last_cwd will be consumed by the upcoming auto-respawn commit
to spawn the shell at the right directory.
