Function remainingAfterFinalizedPrefix

remainingAfterFinalizedPrefix(
full: string,
finalizedPrefix: string,
): CumulativePrefixMatch
Returns the unfixed suffix of cumulative transcript after text already emitted as finals.

Providers (especially AssemblyAI with format_turns) revise punctuation and mid-turn wording — e.g. finalized …David. then cumulative …David had…. Word-level alignment keeps those revisions from re-emitting earlier captions.
Parameters
- full: string
  Latest cumulative transcript.
- finalizedPrefix: string
  Text already emitted as caption finals.
Returns CumulativePrefixMatch
Remaining text plus how the prefix was matched.
