Deletes the V1 rich-text engine and the extensions/ tree. The public
document model flips from WordsDocument to WordsDocumentV2 (D1: V2 puro,
sin legacy — no backward-compat importer, V1-persisted docs no longer
load). Per D2, table striped/compact/cell-tone are dropped entirely
(props, commands, morfo attrs).
- Delete engine/{document,operations,commands,history,input,render,
find-replace,serialize-{html,json,markdown,text},dom-selection,index}
and the whole extensions/ tree (registry + image + table).
- Complete the V2 ops under operations-v2/: port commands, history,
input, find-replace, render-dom, serialize-text, extra-ops,
insert-block-types, markdown shortcuts, factories, dom-selection;
land R4A.2-R4A.8 (text/delete/marks-ops/paragraph-ops/delete-ops/
block-format/list-ops/link-ops/table-ops/selection-walkers).
- Rewire provider, exports, types, morfo/words.ts, eidos word
components, soma words.svelte, the content-test harness, and the
/uix/components/words demo to V2.
- Import accepts JSON (JSON.parse + validateWordsDocument gate) and
plain text only; HTML and Markdown remain export-only (lossy, no
faithful inverse parser).
Verify: npm run check 0 errors; words scope 455/456 (lone failure is the
sema-parity 5s timeout flake under parallel load — 6/6 isolated);
morfo:vocabulary exit 0; browser smoke of /uix/components/words green
(sample renders, text + JSON import round-trip, invalid JSON rejected
without mutating the doc).
