The copy link button rendered its icon as a Material Symbols ligature text node, and since the button is appended inside each heading's `.docs-anchor`, that text leaked into the heading and the Algolia crawler indexed values like `Descriptionlink`. The glyph is now rendered via a `::before` pseudo-element using the icon codepoint, so no `link`/`check` text exists in the DOM and headings index correctly again.
Follow-up to #69205. After switching adev's COEP to `credentialless`, the
cross-origin YouTube iframe in `<docs-video>` loads in Chromium and Safari but
not Firefox, whose `credentialless` policy does not extend to nested frames. The
result was a COEP error screen instead of the player.
Render `<docs-video>` as a lightweight thumbnail facade instead of embedding the
iframe directly. The thumbnail is a cross-origin subresource, so it loads under
`credentialless` in every browser. `DocViewer` then upgrades the facade to the
inline player on hydration in browsers that can load the embed (Chromium,
Safari), preserving the previous behavior there. On Firefox the facade stays a
plain link that opens the video on YouTube (with autoplay), which replaces the
error screen.
The thumbnail uses `maxresdefault` and falls back to `hqdefault` when a video
has no max-resolution image.
Remove usages of `detectChanges` and rely on `whenStable`.
This commit also removed the usage of `provideZonelessChangeDetection` which is no longer necessary.
Rather than using multiple view modes for code examples, we can just treat the previous snippet mode as
as multifile mode that just only has one file in it.
This commit moves zoneless from experimental to developer preview.
* Update tag on provider API
* Remove "experimental" from provider name
* Move documentation from "experimental features" to "Best practives ->
Performance" (at least temporarily until there is a better place)
BREAKING CHANGE: `provideExperimentalZonelessChangeDetection` is
renamed to `provideZonelessChangeDetection` as it is now "Developer
Preview" rather than "Experimental".

To increase the ease of development we are moving @angular/docs into the adev directory within this repo. While
we are doing this to improve our development experience in the short term, efforts are also in place
to maintain a division between this @angular/docs (shared) code and adev itself, so that it can be extracted
back out in the future when components is ready to leverage it as well.
