Replaces the single-shot ephemeral VM approach:
- --prepare: create VM, install deps (Rust, cmake, etc), upload source
- --build: build on VM with full output (iterate on errors)
- --transfer: download binaries to target/linux-x86_64/
- --destroy: delete VM when done
- --upload: re-upload source to existing VM
- --all: prepare + build + transfer (VM persists)
VM reuse: --prepare detects existing wzp-builder VM and just re-uploads.
All steps get VM IP from hcloud server list (last created).

Web playback rewritten from push-scheduling to pull-based ring buffer:
- ScriptProcessorNode pulls frames from buffer every ~21ms
- Buffer capped at 10 frames (~200ms) — drops oldest on overflow
- Latency permanently bounded, no drift over time
Also: install ring crypto provider for rustls TLS on Linux,
build on debian-12 to match mequ glibc.

- cpal is now behind an 'audio' feature flag (off by default)
- --live mode requires --features audio at build time
- --send-tone and --record work on headless servers without audio libs
- Linux build script no longer installs libasound2-dev
Build for headless: cargo build --release
Build with mic/speakers: cargo build --release --features audio

CLI modes:
- --send-tone <secs>: send 440Hz test tone (no mic needed)
- --record <file.raw>: save received audio to raw PCM file
- --help: usage info
- Combine: --send-tone 10 --record out.raw
Raw PCM format: 48kHz mono s16le
Play with: ffplay -f s16le -ar 48000 -ac 1 out.raw
Build scripts:
- scripts/build-linux.sh: Hetzner VPS build with auto-cleanup
- scripts/cleanup-builder.sh: kill stale builders
