* fix: detect Tencent SILK (\x02 prefix) in audio magic bytes to avoid ffmpeg failure QQ official bot sends voice in Tencent SILK format (leading \x02 byte before #!SILK_V3 magic). _get_audio_magic_type() had two off-by-one slice errors: 1. Standard SILK: header[:8] vs b'#!SILK_V3' (8 != 9 bytes) — never matched 2. Tencent SILK: not detected at all Fixes: - Standard SILK: header[:9] == b'#!SILK_V3' (correct 9-byte slice) - Tencent SILK: header[:1] == b"\x02" and header[1:10] == b'#!SILK_V3' - ensure_wav() routes detected silk to tencent_silk_to_wav() Before: QQ voice → ffmpeg → 'Invalid data found' After: QQ voice → magic detects silk → tencent_silk_to_wav → WAV OK * refactor: use startswith() for SILK magic byte detection Replace manual slice comparisons with startswith() — cleaner, less error-prone, and immune to off-by-one slice errors.
