install_parakeet_model: drop wrong -coreml suffix from MAC_FLUIDAUDIO_REPO_NAME
The lode-shipped value parakeet-tdt-0.6b-v3-coreml did not match the
directory FluidAudio v0.14.0 actually writes on Apple Silicon. Empirically
re-verified by direct helper invocation against a fresh /tmp cache dir on
Mac17,9 / Apple M5 Pro, FluidAudio v0.14.0:
parakeet-helper --cache-dir /tmp/freshtest/cache ... --model v3 ...
-> wrote to /tmp/freshtest/parakeet-tdt-0.6b-v3/
So the constant must be parakeet-tdt-0.6b-v3 (no -coreml suffix) for
_verify_mac_cache to land on the actual model files. Without this fix,
make install-models on darwin/arm64 still exited 1 with macOS cache
verification failed even with the FluidAudio-resolved-path fix in place.
