Garry Tan 70b59ec91b fix(make-pdf): decode HTML entities in titles and TOC to prevent double-escape
A markdown title like "# Herbert & Garry" rendered as "Herbert & Garry"
in <title>, cover block, and TOC entries. marked emits "&amp;" (correct HTML),
but extractFirstHeading and extractHeadings only stripTags — leaving the entity
intact. That string then flows through escapeHtml, producing the double-encode.

- render.ts: new decodeTextEntities helper, distinct from decodeTypographicEntities
  (which runs on in-pipeline HTML and intentionally preserves &amp;). Covers
  named entities (lt/gt/quot/apos/39/x27/amp) AND numeric (decimal + hex) so
  inputs like "&#169;" or "&#x2014;" don't create the same partial-fix bug.
  Amp-last ordering prevents double-decode on "&amp;lt;" et al.
- Apply in both extractFirstHeading and extractHeadings. extractHeadings feeds
  buildTocBlock → escapeHtml, so the TOC site had the same bug.
- render.test.ts: 8 tests covering the contract — parameterized across &, <, >,
  ©, — chars; single-escape in <title>/cover; TOC double-escape check; numeric
  entity decode; smartypants-interacts-with-quotes contract (no raw equality).
