Add two subcommands and the deps they need, shipped as madcat-say 0.1.0.
gpu-check (Sources/GpuCheck.swift)
Queries the Metal device and runs a small MLX compute probe to verify
the GPU pipeline + bundled mlx.metallib resolve before synth.
serve (Sources/Serve.swift)
Loopback HTTP daemon (default 127.0.0.1:8765, Hummingbird). Loads
VoxCPM2 once behind an actor (serializes the single GPU), warms the
pipeline at boot, caches the last reference voice. Routes:
GET /health -> {status,model,ready,uptime_s}
POST /v1/audio/speech {input|text, voice?, language?, timesteps?,
cfg?, prepad?} -> audio/wav
Cuts warm synth to ~3.2s vs ~6.3s cold (in-process model load).
speak (Sources/MadcatSay.swift)
Probes the daemon /health (0.6s) and forwards over HTTP when up;
falls back to in-process load otherwise. New flags --daemon-port,
--no-daemon.
Package.swift: add mlx-swift (GPU probe) and hummingbird 2.5..<2.17
(HTTP only, no WebSocket — avoids the swift-websocket pin).
Makefile: resolve the metallib via `swift build --show-bin-path` on
both packages instead of the triple-prefixed/symlink path, which is
not always present in speech-swift.
