fix(audio): eliminate startup delay with automatic buffer pre-fill
Added audio_get_required_prefill_time() to query ring buffer lookahead
(400ms) and audio_is_prefilled() to check buffer state. audio_start()
now warns if buffer under-filled. Replaced hardcoded 100ms pre-fill
with automatic target-based pre-fill in main.cc and test_demo.cc.
