- Replace buffer.index() with buffer.buffer_mut()/buffer.buffer() (ndk 0.9 RAII API)
- Replace queue_input_buffer_by_index/release_output_buffer_by_index with
queue_input_buffer/release_output_buffer taking buffer objects
- Fix MaybeUninit<u8> copy using .write() instead of copy_from_slice
- Add BITRATE_MODE_CBR and AMEDIACODEC_BUFFER_FLAG_KEY_FRAME local constants
(removes ndk_sys dependency for these values)
- Add unsafe impl Send for all six MediaCodec wrapper structs
- Pin @tauri-apps/api to ^2.11 to match Cargo.lock tauri 2.11.1
