Echo 2.3.0

• What's New never clips: standard sheet sizes and a scroll view.
• Speak-Back Voice shows one row per voice, best quality, with the region when a name has two accents.
• Models read Auto, Apple, Tiny, Base, Small, Large.
• The account's sign-in token is this-device-only.
• Apple first: engine-level tests, including a stop pressed while Apple's session is still starting. A failed start no longer leaves a listener hanging.
• Benchmarks: Apple 65x real time, Whisper tiny 57x, base 51x, small 16x on a Mac mini M4 (docs/BENCHMARKS.md).
• TranscriptionEngine split by area into Models, Live, Apple and Files.
