/** CDXC:SessionChat 2026-09-17 WHY:
* Pi, OMP, Hermes, Antigravity, and ZCode terminals preserve single newlines in assistant replies, including emoji glyph lists that CommonMark otherwise collapses into one paragraph; the ZCode TUI paints every soft-break newline as its own row.
* Supersedes the 2026-09-14 wording, which predated ZCode becoming a chat agent family.
* Apply this only to assistant prose, keeping reasoning normalization and user quote handling independent.

* User: ZCode joins the preserve list — its replies are written one row per line for the terminal, so chat must not collapse them.
