Address the non-test code-review findings on the htmlEmbed sandbox change
(test-coverage gaps are tracked in issue #99):
- html-embed-view: track the iframe's reported content height even while a
fixed height is set, so clearing the height (fixed -> auto) without editing
the source no longer leaves the frame pinned to the stale value. Derive the
fixed-height predicate once; seed autoHeight to the default.
- html-embed-view: drop width/border from the iframe inline style (the
.htmlEmbedFrame CSS class already provides them).
- html-embed-sandbox: coalesce height reports via requestAnimationFrame and
skip <=1px deltas to damp the self-measure feedback loop; fix the misleading
bootstrap comment.
- tracker-settings: add an aria-label to the snippet Textarea (a11y).
- CHANGELOG: note the removal of server-side role-based HTML-embed stripping.
Follow-up fixes to the htmlEmbed-sandbox / trackerHead change:
- share-seo: inject trackerHead via a function replacer so `$`-sequences
($&, $', $`, $$) in the admin snippet are inserted literally instead of
being treated as String.replace substitution patterns; warn when the
</head> marker is absent instead of silently skipping injection.
- mcp: register a passthrough `htmlEmbed` node in the schema mirror so an
AI/MCP edit of a page containing an embed no longer throws
"Unknown node type: htmlEmbed" in TiptapTransformer.toYdoc.
- editor-ext + client: treat a non-finite `data-height` as auto (null) so a
crafted/corrupted height cannot disable auto-resize or yield a NaN iframe
height; extract a shared clampHeight helper.
- client: rename render-raw-html.{ts,test.ts} -> html-embed-sandbox.{...} and
shouldExecute -> shouldRender so the seam name matches the sandbox model.
- client: i18n the iframe title; surface the real error reason in
tracker-settings (console.error + err.response.data.message).
- docs: note hasHtmlEmbedNode is now a test-only helper; add an Unreleased
CHANGELOG entry; drop the dangling "arbitrary HTML embed" planning-doc ref.
