PeerSpeak — Windows installer

This directory builds a Windows setup installer for PeerSpeak using Inno Setup.

PeerSpeak ships as a single self-contained peerspeak.exe — the GUI icon, notification chimes, and avatar presets are all embedded in the binary (include_bytes!), and the executable is statically linked against the GNU runtime, so there are no extra DLLs to bundle. The installer payload is just the .exe plus an .ico for the Start-menu / desktop shortcuts.

Version compatibility

The installer version tracks the crate version in Cargo.toml (currently 0.4.0) — keep MyAppVersion in peerspeak.iss in sync when it changes.

Per VERSIONING.md, a MINOR bump in 0.x is a breaking wire change: peers on different MINOR versions can't connect (they fail fast at the handshake rather than misbehaving). So when you ship a new Windows build after a MINOR bump, everyone on the call must reinstall — an old Windows build and a newer Linux/Windows peer won't talk. (0.3.0 was the chat file-sharing + per-peer noise-gate release; it cannot connect to a 0.2.x peer.)

Files

File	Tracked	Purpose
`peerspeak.iss`	yes	Inno Setup script
`peerspeak.ico`	yes	multi-resolution app icon (from `assets/icons/*.png`)
`README.md`	yes	this file
`peerspeak.exe`	no (gitignored)	staged build artifact, copied from `target/x86_64-pc-windows-gnu/release/`
`output/peerspeak-<ver>-setup.exe`	no (gitignored)	the compiled installer

Build steps

Cross-compile the Windows binary (from the repo root, inside the peerspeak-win archlinux distrobox):
```
RUSTC_BOOTSTRAP=1 ./win-cross-build.sh -Z build-std=std,panic_abort
```
This needs the rust-src component and the x86_64-pc-windows-gnu target installed in that toolchain. The result is a statically-linked, GUI-subsystem .exe (no stray console window).

Stage the binary next to the script:

cp target/x86_64-pc-windows-gnu/release/peerspeak.exe packaging/windows/

Regenerate the icon if the source PNGs changed:

magick assets/icons/peerspeak-16.png assets/icons/peerspeak-24.png \
       assets/icons/peerspeak-32.png assets/icons/peerspeak-48.png \
       assets/icons/peerspeak-64.png assets/icons/peerspeak-128.png \
       assets/icons/peerspeak-256.png packaging/windows/peerspeak.ico

Compile the installer with Inno Setup. On Linux this runs under Wine:
```
cd packaging/windows
wine ~/.wine/drive_c/InnoSetup6/ISCC.exe peerspeak.iss
```
The installer lands at output/peerspeak-<version>-setup.exe.

What the installer does

Installs peerspeak.exe to Program Files\PeerSpeak (requires admin / one UAC prompt).
Creates a Start-menu shortcut, with an optional desktop shortcut.
Optionally adds a Windows Firewall allow-rule for PeerSpeak (recommended — iroh uses UDP hole-punching, so this avoids a mid-call firewall prompt). The rule is removed on uninstall.
Provides a standard uninstaller.

Note: the installer and the binary are not code-signed, so Windows SmartScreen will show an "unknown publisher" warning on first run. The user clicks More info → Run anyway. Removing this warning requires a paid code-signing certificate.
