v2.2.4

Improvements

• Curved icon everywhere (squircle) — The app now uses the same curved-radius icon on all platforms. build-dock-icon.js generates code-automata-dock.png and code-automata-dock-light.png from the main icon (~22% rounded corners and zoom). This icon is used for the macOS app bundle (Finder, dock), dock/menu bar at runtime, Windows .ico, Linux PNGs, and fallback; the square icon is only an intermediate build step.
• Next.js standalone build — prepare-build.js flattens nested .next/standalone when Next.js outputs a duplicated structure, so the packaged app always finds server.js in the expected location.
• Node.js 18+ for packaged app — Main process prefers Node 18+ (required for Next.js 15), with nvm-aware ordering (newest first) and fallback to any installed version. Resolves correct binary when multiple Node versions exist.
• Server startup — Startup timeout increased to 45 seconds. On failure (node not found, wrong version, or timeout), the loading screen shows clear instructions to install Node 18+, add it to PATH, and restart the app.
• Release workflow — Manual "Run workflow" can accept a tag (e.g. v2.2.4) to build and publish that release when tag push does not trigger. Note added that runs may appear 5–15 minutes after tag push.

Build & Release

• Icon pipeline — Single source public/code-automata.png; build-mac-icons.js produces code-automata-dark.png (1024×1024); build-dock-icon.js produces the curved code-automata-dock.png used for the app icon, Windows/Linux, and dock. All builds run the dock-icon step so the curved asset exists before build-icons.js. public/**/* included in packaged app.
