Let the cleanup model fix the sentence, not just the words

The dictation prompt asked for minimal interference, so it repaired what
sits inside a sentence (filler, stutters, a misheard proper noun) and left
the sentence itself as it was spoken. Speech does not come out in sentences.
A thought gets started, an aside comes in, the verb is said again on the
other side of it, and the same point comes back around three sentences
later; all of that survived cleanup and had to be edited by hand afterwards.

The prompt now reads the whole transcript first, reduces a thing said twice
to the clearest telling, and repairs the sentence: hanging clauses, subject
and verb, a sentence that ran on while it was being spoken. What it must not
do is spelled out at more length than what it must, because this is the side
that can lose a dictation rather than tidy it. Nothing may be added, nothing
summarised away, the register stays the speaker's own, and a sentence whose
meaning is unclear is left exactly as it arrived.

The outgoing defaults join LEGACY_PROMPTS so that a config which copied one
in follows the new default instead of shadowing it.

Subtitle cleanup is untouched: a subtitle is read while the same words are
being heard, and this kind of tidying would pull it out of sync.
