"""Regenerate docs/re/data/preset-messages.txt.

The reactive combat-chatter system: a per-character *rule* table
(`message\\PresetMessage_<who>[_<NN>][_S<stage>-<phase>].tbl`) holding 64 event
records plus a `Sperkers` speaker roster, paired with a `_msg.tbl` message table
in the layout cutscene-message-table.md already documents.
