chore(words): sweep D2 orphans from eidos CSS + README

Removes now-dead selectors left after V2 dropped table striped/compact
and cell tone/header (D2). Nothing emits these attrs anymore:
- `[data-command='table-cell-tone-*']` toolbar rules
- `table[data-words-table-striped]` / `[data-words-table-compact]` rules
- `[data-words-cell-tone='muted'|'accent']` cell + focus-within rules
- the dead `[data-words-cell-header]` alternates (headers render as <th>);
  `tr:hover td:not([data-words-cell-header])` simplified to `td`

README updated: tables list only the live formatting (header row/column,
cell align, vertical align); HTML/Markdown documented as export-only,
import as JSON + plain text. ARCHITECTURE_PROPOSAL keeps its mentions —
they document the decision to drop these, not stale features.

Verified in browser: sample 2x2 table renders, <th> keeps the accent
tint + weight via :where(th), cell align/vertical intact, no console
errors. CSS + Markdown only — no type surface touched.
