Realtime Translate Subtitles

- Brand New "Push-to-Talk (PTT)" Mode: Experience our redesigned, high-precision press gesture for recording. Tap and hold to speak, release to stop—perfect for capturing single-sentence inputs with higher precision. - Smart Language Pair Filtering: We now dynamically filter out unsupported offline translation directions, displaying only valid local translation pairs for a cleaner, error-free selection screen. - Deep Microphone & Battery Optimization: Redesigned microphone lifecycles now instantly deactivate the audio session as soon as recording ends. This completely resolves the lingering iOS microphone status indicator and improves battery efficiency. - Subtitle Persistence Bug Fix: Fixed a visual issue where previous translated subtitles would linger on the screen after switching source or target languages. - Landscape Large Subtitle Upgrades: Added an offline language download warning Banner in the immersive landscape mode, complete with system permission recovery and a seamless, one-tap shortcut to iOS Settings.
