* fix(tts): report actual audio output formats Detect local CLI audio containers before conversion and derive ElevenLabs delivery metadata from the effective output format. This prevents MP3 or PCM bytes from being persisted or delivered under incompatible file and voice metadata. * fix(tts-local-cli): distinguish Ogg Opus audio Treat Ogg as a source container unless its first packet is OpusHead, so Vorbis and M4A inputs are transcoded to the requested target instead of being mislabeled as native voice audio. * fix(tts-local-cli): validate MP3 frame headers Require valid MPEG version, layer, bitrate, and sample-rate fields before treating sync bytes as MP3, preventing reserved headers from bypassing conversion under MP3 metadata. * fix(tts-local-cli): validate tagged MP3 output Require structurally valid ID3v2 metadata followed by a strict MPEG frame, and stop trusting recognizable file extensions when their bytes do not match. Unknown or malformed output now fails closed instead of bypassing conversion. * fix(tts-local-cli): accept free-format MPEG audio Treat bitrate index zero as valid free-format MPEG audio and lock the ID3v2.4 footer offset contract with focused regression coverage. * fix(tts-local-cli): normalize all Ogg output Treat Ogg only as a source container and always transcode it to the requested target, so malformed or ambiguous Ogg bytes can never bypass conversion as native voice audio.
