* fix(linux): draw the macOS tray icon from a template silhouette
AppKit renders menu bar template images from the alpha channel alone, so the
opaque rounded-tile 32x32.png painted a solid white square instead of the
mascot. Add a dedicated tray-template.svg and its 36px render, a silhouette
with the eyes knocked back out, and select it only on macOS. Its geometry
mirrors the native macOS app's CritterIconRenderer at rest so both clients
wear the same face; other platforms keep the full-color 32x32.png.
* chore(linux): drop the root changelog entry from the tray icon fix
CHANGELOG.md is release-owned in this repo (AGENTS.md) and `scripts/pr
prepare-run` rejects normal PRs that touch it; release generation derives
entries from merged PRs. The release-note context lives in the PR body and
the preceding commit message instead.
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).
