Repair only what is deterministic

Whitespace cleanup, blank-line cleanup and sequence renumbering are explicit fix classes. Removing duplicate dialogue is kept opt-in because two identical cues can occasionally be intentional.

Diagnostics stay truthful

After a repair, the file is validated again from its actual state. An unrelated fix does not make a missing sequence or other unresolved issue disappear.
