Pull request overview
Adds visibility into a definition’s alternate “linking terms” (from data-lt) by rendering them in the DFN panel, addressing the usability request in #3741.
Changes:
- Render a “Linking terms:” line in the DFN panel when
data-ltis present and contains aliases beyond the DFN’s own text. - Normalize/dedupe
data-ltvalues for display and omit the term matching the DFN’s text content. - Add a spec test covering presence/absence and whitespace normalization behavior.

Adds a "Possible linking syntaxes:" section to each dfn popup panel,
showing the correct ReSpec inline shorthand for linking to the definition.
Handles all dfn types: [= =] for concepts, {{ }} for IDL, [^ ^] for
elements/attributes, {^ ^} for CDDL. Includes data-lt aliases and per-item
copy-to-clipboard buttons. Fixes selectors in dfn-index-spec.js.
Closes #3741
- Add "interface mixin" and "callback interface" to IDL_TYPES - Add removeOnSave to copy buttons so they're stripped from exports - Include buttons in trapFocus selector (a11y: keyboard users can reach copy buttons)

Split comma-separated data-dfn-for values so each produces a separate
linking syntax (e.g. {{Foo/method()}} and {{Bar/method()}} instead of
the invalid {{Foo, Bar/method()}}). Also skip primaryTerm when
data-lt-noDefault is set, matching getDfnTitles behavior.
