Reject phantom speakers invented from German noun phrases (v1.20.35)

The caster emits fragments of noun phrases as characters — "in seinem Inneren"
-> Inneren, "die Hand" -> Hand, "mein Geliebter" -> Geliebten, "der Wind" ->
Wind. Each became a cast entry with its own voice while the real speaker's line
was lost to a phantom; measured against a hand-corrected book this was a large
part of why a fresh cast produced 73 speakers where the human had 62.

Such lines are now reset to Unknown — visibly unresolved and still recoverable
by the repair passes, rather than silently wrong. Applied to a real cast:
5 phantoms removed, 73 -> 68 speakers.
