LRC to SRT Converter

LRC only stores the start time of each lyric line. We set each line's end time to the next line's start (capped at 8 seconds to avoid dangling text on pauses). The final line defaults to 4 seconds.

Inline per-word tags like <mm:ss.xx> are stripped; the line-level timestamp at the start of each lyric is what matters for SRT output.

Metadata tags (title, artist, album) are silently skipped; they are not subtitle cues.
