+Electron 44, and dependency updates. No change to how the app behaves.

+#### Changed

+- **Electron 44** (44.4.5, Chromium 152), up from 43 (#310). Nothing this app
+  uses is among its breaking changes: it drops 32-bit Windows and macOS 12, and
+  the wall's build is 64-bit Windows. WebGL2, the capture path and the
+  screensavers were checked on it before merging
+- Development dependencies updated: eslint 10.10, vite 8.2.2, globals 17.12 and
+  fast-uri 3.1.7; the release workflow's `action-gh-release` to 3.0.3, still
+  pinned to a full commit SHA (#301, #303, #304, #308, #309)

+- **A dev window could run another checkout's code.** `npm run dev` always loaded
+  the renderer from port 5173, so when another checkout's dev server held that
+  port, the window showed that checkout's code without any warning. It now loads
+  from the port Vite actually used, and logs it. Packaged builds are unaffected
