fix(sound): recover port 57121 from zombie on boot
CI build oscope-of / build-check (push) Has been cancelled
Details

Browse Source 
The data-only boot opened the OSC receive port 57121 but fell back
silently to the lang port when it was busy — so /pose (data_only_viz)
and /data (data_feeds bridge), both sent to 57121, never reached
sclang and the patch looked alive but reacted to nothing. The port is
typically squatted by a zombie: a scsynth or data_feeds bridge launched
by a previous boot via unixCmd inherits the 57121 socket FD and outlives
its sclang parent, so a fresh boot can't bind it. Instead of falling
back, free the stale holder (lsof -ti UDP:57121 | xargs kill -9) and
retry openUDPPort. Verified: a planted zombie on 57121 is killed and the
port recovered on boot ("57121 recupere — sclang listening on 57121").
