feat(macos): local ASR model manager, menu-bar polish, and release 0.5.2

Adds a bundled local ASR model catalog for the macOS app with one-click Sherpa Qwen3 / SenseVoice downloads (pause/resume, inline actions) and a shared model storage directory used by MLX Qwen3. Fixes the light-mode sidebar material and makes the menu-bar icon follow the system appearance with a refreshed status mark. Renames the built product to OSGKeyboard.app. Bumps version to 0.5.2 (build 19).
