windows: docker + hcloud build scripts for cross-compile
Two parallel paths to build wzp-desktop.exe for x86_64-pc-windows-msvc:

scripts/Dockerfile.windows-builder
  Debian 12 base, matches scripts/Dockerfile.android-builder's layout:
  - apt: build-essential, cmake, ninja-build, llvm, clang, lld, nasm,
    libssl-dev, node 20 LTS
  - rust stable + x86_64-pc-windows-msvc target
  - cargo-xwin pre-installed
  - Pre-warmed ~/.cache/cargo-xwin layer: creates a throwaway cargo
    project and runs `cargo xwin build` once during image build so the
    MSVC CRT + Windows SDK (~1.5 GB) is baked into an image layer.
    Saves ~4 minutes off every cold cross-compile run.
  - Builder user uid 1000 to match existing bind-mount perms on
    SepehrHomeserverdk.

scripts/build-windows-docker.sh
  Same pattern as scripts/build-tauri-android.sh but for Windows:
  - Fires a remote build on SepehrHomeserverdk via ssh + heredoc
  - Mounts the shared cargo-registry + cargo-git cache + a
    target-windows dir (separate from the android target cache so
    different triples don't stomp each other)
  - Runs npm install + npm run build for the frontend dist, then
    cargo xwin build --release --target x86_64-pc-windows-msvc
    --bin wzp-desktop inside the container
  - Uploads the resulting .exe to rustypaste (via the .env token on
    the remote, same as android script) and fires ntfy.sh/wzp
    notifications at start + completion
  - scp's the .exe back to target/windows-exe/wzp-desktop.exe locally
  - --image-build flag triggers a fire-and-forget `docker build` of
    the Dockerfile.windows-builder on the remote (used once after the
    Dockerfile changes). The image is already built at the moment of
    this commit — sha256:f3895cb2fde7

scripts/build-windows-cloud.sh
  Kept as an alternative cross-compile path using a fresh Hetzner VM
  (cx33, 8 vCPU, 8 GB — bumped from cx23 after the smaller size OOM'd
  mid-rustc). The docker-on-SepehrHomeserverdk path is now the
  preferred fast path because the image has a pre-warmed xwin cache
  and a persistent cargo target volume, making warm builds ~3 minutes
  vs the cloud path's ~20 minutes cold each run. The cloud script
  stays around for when we want a truly isolated environment.

Both scripts notify via ntfy.sh/wzp and upload to paste.dk.manko.yoga
so the user can pick up the artefact + see status without polling.

# WZ Phone — Windows x86_64 cross-compile (Docker on SepehrHomeserverdk)
#
# Cross-compiles the Tauri desktop binary for Windows via `cargo xwin`
# inside the wzp-windows-builder Docker image on SepehrHomeserverdk.
# Uploads the resulting .exe to rustypaste, fires ntfy.sh/wzp notifications
# at start + finish, and SCPs the .exe back locally.
#
# Same pattern as build-tauri-android.sh but for the Windows cross-compile
# pipeline:
# - Source: desktop/src-tauri/
# - Build: cargo xwin build --release --target x86_64-pc-windows-msvc
# - Output: target/x86_64-pc-windows-msvc/release/wzp-desktop.exe
#
# Usage:
# ./scripts/build-windows-docker.sh # full pipeline
# ./scripts/build-windows-docker.sh --no-pull # skip git fetch
# ./scripts/build-windows-docker.sh --rust # force-clean rust target
# ./scripts/build-windows-docker.sh --image-build # (re)build the docker image
#
# Environment:
# WZP_BRANCH Branch to build (default: feat/desktop-audio-rewrite)
