Esperanto as a text language (#1142) (#1204)

Esperanto in Character › Language (panel, Properties, style options),
mapped to the BCP 47 tag eo, with English-style typographer's quotes.
IDML keeps the name as written ($ID/Esperanto). Not hyphenated yet:
morpheme-based hyphenation follows in #1201.

 ## Progress log
 
 - **2026-11-04** · Striped strokes retain out-and-back cubic segments whose second control point is away from the coincident endpoints and first control point. A geometry regression checks the offset extent and both stripe bands. No readiness percentage change.
+- **2026-11-04** · Esperanto is a text language (Character › Language, `type.char {language: "Esperanto"}`, IDML `$ID/Esperanto`): tag `eo`, English-style quotes; not hyphenated yet (#1201). No readiness percentage change.
 
 - **2026-11-02** · EPUB Export Options names a cover image file (PNG or JPEG, typed or chosen with Choose…) for the reflowable export; left empty, the first page stays the cover (#1934). No readiness percentage change.
 - **2026-11-02** · The Pen shows the segment a dragged smooth point shapes while it is dragged, and its rubber band curves out of a smooth point's direction line (#1438, first item). No readiness percentage change.
