cargo-ndk doesn't always copy libc++_shared.so into jniLibs. The
build script now finds it in the NDK and copies it manually if
missing, preventing the build check from failing.

Both Android and Linux build scripts now send ntfy notification
when build fails, not just on success.

Same Docker image as Android build. Separate cache dirs (cache-linux/)
to avoid conflicts when running both builds simultaneously.
Builds: wzp-relay, wzp-client, wzp-client-audio, wzp-web, wzp-bench
Uploads tar.gz to rustypaste, notifies ntfy.sh/wzp.
Usage:
./scripts/build-linux-docker.sh --pull # fire and forget
./scripts/build-linux-docker.sh --pull --install # wait + download

Relay identity:
- Stored in ~/.wzp/relay-identity (hex-encoded 32-byte seed)
- Generated on first run, reused on restart
- Fingerprint stays consistent across relay restarts
Linux build script (scripts/build-linux-notify.sh):
- Fire and forget: Hetzner VM → build all binaries → upload to rustypaste → ntfy notify → destroy VM
- Builds: wzp-relay, wzp-client, wzp-client-audio, wzp-web, wzp-bench
- Packages as tar.gz, uploads to rustypaste
- --keep flag to preserve VM

- AudioPipeline.debugRecording defaults to false (was true)
- SettingsRepository: persist debug_recording preference
- CallViewModel: debugRecording StateFlow + setter, wired to AudioPipeline
- Only records PCM + RMS when explicitly enabled in settings

The jni crate emits VERBOSE logs for every JNI method lookup (~10 lines
per call, 100+ calls/sec on audio threads). This floods logcat, consumes
CPU, and triggers system kills. Filter to only show INFO+ for our crates
and WARN+ for everything else.
Also fix build script: clean full Rust target to ensure libc++_shared.so
is always copied by cargo-ndk.

- Filter hcloud by SERVER_NAME to avoid touching other servers
- Use rsync instead of tar (handles submodules, no macOS xattr spam)
- Default server type cx33
- Release APK failure is non-fatal (debug APK still produced)

cmake 3.28 works when ANDROID_NDK is set (not just ANDROID_NDK_HOME).
Relaxed version check from <=3.26 to <=3.30.

Documents WHY each version is pinned:
- cmake 3.25: 3.27+ rewrote Android-Determine.cmake with bugs
- NDK 26.1: NDK 27 scudo crashes on MTE devices (Nothing A059)
- JDK 17: Gradle 8.5 + AGP 8.2.0 official support
- ANDROID_NDK: cmake checks this, not ANDROID_NDK_HOME
Idempotent, works from clone or existing tree.

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
