Fixes #4008.

Worker-fallback extractHtml (pkgs/lab-ops-hub/src/lib.ts) now mirrors the container Extractor's HTMLParser modes for the five elements issue #4008 names:

• textarea is RCDATA: content is character data (entities decoded, markup literal) up to the matching </textarea>, and it contributes body text. The reported case <textarea><script></textarea><p>Article body</p> now yields <script> Article body, identical to the container (the Worker returned empty text).
• iframe, xmp, noembed, noframes are raw text: content is literal up to the matching close tag (anchors inside never count as links) and is reported verbatim — no entity decoding — as ordinary character data, exactly as HTMLParser delivers it to the container Extractor.
• Unterminated regions: the container only ever calls feed() (container/app.py never calls close()), so an unclosed raw-text/RCDATA tail stays unflushed and is dropped; the Worker now drops it too for these five elements. Script/style/title EOF handling is unchanged.

Fixtures: 10 new container-verified cases in test/extractor-fixtures.json (the reported example plus at least one per element, an entity-verbatim case, both unclosed cases, and a trailing-attribute close tag), each generated from the container Extractor and pinned in both suites.

One clarification vs the issue text: the acceptance says iframe/xmp/noembed/noframes content is "skipped" — container-verified behavior is that the content is skipped as markup (never parsed for tags/links) but delivered as literal text; the fixtures encode the verified behavior.

Tests (laptop, this branch):

• npm run test:ts — 99 pass, 0 fail.
• test_extractor_parity.py — OK (all 39 fixtures, both directions).
• npm run test:py — 69 tests, 1 pre-existing error in test_container_validate (test_returns_idn_hosts_in_alabel_form, IDNA judging in container/app.py under Python 3.14; that code is untouched by this diff and the deployed container pins Python 3.13).

Queue: task 8964, lane code-n.
