The bundle/tray icon (icon.svg, icon-tile.svg and the generated
32/128/256/512 PNGs + icon.ico) still used the abstract two-pill
claw-mark. The product logo is the Clawd lobster mascot (already used in
the app header and ui/public/favicon.svg), so the app icon shown in the
Dock, taskbar, window, and tray now matches it: a static mascot on the
dark brand tile (transparent mascot for the tray). Regenerated from the
mascot SVG via rsvg-convert; build accepts the icon set.
The desktop companion crate was Linux-only. All platform-specific code
lives in canvas.rs (WebKitGTK, cairo, unix sockets, SO_PEERCRED), so:
move webkit2gtk/cairo-rs/libc under linux target dependencies, gate the
canvas module, its protocol registration, invoke handler, and exit
shutdown to Linux, add a USERPROFILE home fallback and an explicit
no-op installer error for Windows, and add the multi-size icon.ico
Windows resource. Linux behavior is unchanged; macOS/Windows builds are
for testing (macOS cargo build+test green locally; Windows aarch64-msvc
built and launched in a Windows 11 ARM VM).
