Spoken lines that PDF extraction typed as narration were invisible to
"Identify unknown characters" (it only scans type==='dialogue'), so no number
of re-runs could fix them, while the pass that could re-sent all ~1000
narration segments to the LLM. Adds a detector that scores narration for
direct-speech signals and re-checks only those: 36 candidates instead of 1036
on a real novel. Adds "Auto-repair cast" to chain the passes in the right
order automatically after casting.
Also fixes a rollback gap where stopping a run skipped the safety net that
undoes a pass which increased Unknown speakers (confirmed live: 80 -> 159
with no warning), corrects an attribution rule that taught the model the
listener is the speaker, and stops the threshold loop from re-verifying every
narration segment each round.
