chore(deps): bump @bookhoard/foliate-js to cd2fbf2 — plain-text (.txt) renderer

makeTextBook: UTF-8 decode, blank-line paragraph split, hard-wrapped
lines joined, HTML-escaped, ~150KB section cap at paragraph boundaries
(Part N TOC). Enables the web reader for .txt (previously ingested but
unreadable client-side). Positions for txt books are percentage-based
(sections get index-derived fake CFIs).
