chore: bump version to 0.0.15

- Add ubuntu-24.04-arm and windows-11-arm to CI matrix
- Linux ARM64 builds AppImage + deb (Raspberry Pi, DGX Spark)
- Windows ARM64 builds NSIS installer (Snapdragon devices)
- Add arch to NSIS and AppImage artifact names to prevent collisions
- Add latest-linux.yml and latest.yml merge steps for auto-updater
- Update README with ARM64 download links

Closes #140

+## [0.0.15] - 2026-04-28
+
+### Added
+
+- **ARM64 Support for Linux and Windows.** Native ARM64 builds are now produced for Linux (.deb, AppImage) and Windows (NSIS installer), enabling support for Raspberry Pi, NVIDIA DGX Spark, Snapdragon laptops, and other ARM64 devices (#140).
+
+### Fixed
+
+- **Grey/Blank Screen on Linux.** Disabled GPU compositing entirely on Linux to prevent shared memory allocation crashes that caused a grey or blank screen on systems with restricted `/dev/shm` or `/tmp` permissions.
+- **Spotlight Dismiss Behavior.** Pressing Escape or the toggle shortcut to dismiss Spotlight no longer erroneously brings the main application window to the foreground (#158).
+
+## [0.0.14] - 2026-04-28
+
+### Fixed
+
+- **Grey/Blank Webview on Linux.** Disabled GPU compositing on Linux to prevent silent compositor failures that produce a grey rectangle instead of rendered content on systems with problematic Intel/NVIDIA drivers or certain Wayland compositors (#119).
+- **Renderer Crash Recovery.** The main window now automatically reloads when the renderer process dies unexpectedly, preventing a permanent blank/grey screen.
+- **Webview Crash Diagnostics.** Added logging for guest webview renderer crashes to aid debugging connectivity and rendering issues.
+- **macOS Notarization.** Resolved Apple notarization failure caused by an expired Developer Program agreement, restoring signed and notarized macOS builds.
