Alex 05409403e9 Add Edge TPU subprocess probe to safely detect segfaults ...

Probes the Edge TPU in a subprocess before loading — catches segfaults
(libedgetpu ABI mismatch on Debian Trixie/Python 3.13) and falls back
to CPU automatically. No more service crashes on Coral incompatibility.

When the runtime is eventually fixed, Edge TPU will be used automatically
with no config changes needed.
