Make the tree compile for Windows without touching core logic, by
confining all Linux/PipeWire assumptions behind cfg gates and a single
platform-selected backend alias. No new dependencies — the cpal/WASAPI
backend lands in Phase 1; this ships a no-op stub.
- Cargo.toml: move pipewire + rfd(xdg-portal) under cfg(unix); add a
cfg(windows) rfd using the Win32 dialog backend.
- audio: gate pipewire_impl to unix, add a cpal_impl stub for windows,
and select between them via the new PlatformAudioBackend alias.
- core: use PlatformAudioBackend instead of the concrete PipeWireBackend.
- lib: gate the unix-only 0o600 log-file mode code (+ its test); Windows
logs inherit the directory ACL.
- audio_probe: gate this PipeWire diagnostic to unix with a stub main.
- app: open URLs via rundll32 on windows, xdg-open on unix (shell-free).
- ci: add .gitea/workflows/windows-build.yml (M1) — build + lib tests for
x86_64-pc-windows-msvc, with CMAKE_POLICY_VERSION_MINIMUM=3.5 for the
vendored libopus build. Needs a windows act_runner to actually run.
Linux build/clippy/tests green (316/316). The Windows path is verified by
inspection only (no local Windows toolchain); CI is the real gate.
