Regular code blocks were updated but the citation appendix template was not, making the copy button invisible. Wrap the bibtex 
 in the scaffold div to match.

Subject: [PATCH 3/3] Move #13669 changelog entry to 1.11 and add a regression
 test

The fix ships in 1.11 (QUARTO_VERSION and the issue milestone), so the
entry moves to the Regression fixes section of changelog-1.11.md. It
names v1.8.15 as the release that introduced the regression: 62c71225c
added the code-copy-outer-scaffold wrapper to regular code blocks only,
and the copy button icon and position CSS both key on that wrapper.

The smoke-all test checks the BibTeX block and its copy button share the
scaffold. It fails on main with the scaffold missing.

Also removes trailing whitespace in format-html-appendix.ts.

 - ([#14920](https://github.com/quarto-dev/quarto-cli/issues/14920)): Fix Windows ARM diagnostics for x64 R crashes to preserve the specialized error in `quarto check`, JSON output, and render failures, and update the native ARM64 R installation guidance.
 - ([#14731](https://github.com/quarto-dev/quarto-cli/pull/14731)): Fix `QUARTO_VENDOR_BINARIES=false` builds silently succeeding with missing binaries. The `configure` step's "is it on PATH?" check for `typst-gather`, `typst`, `pandoc` and `esbuild` compared an unawaited `Promise` against `undefined`, so the guard never fired. A build with `typst-gather` neither vendored nor on PATH reported success and produced a Quarto tree without it, surfacing only at render time as `typst-gather analyze failed; staging all packages as fallback`. The missing-binary error message now also names the path that was checked and the `QUARTO_TYPST_GATHER` environment variable.
 - ([#14741](https://github.com/quarto-dev/quarto-cli/issues/14741)): Fix PDF rendering of a cross-referenced table failing with `! Extra }, or forgotten \endgroup.` when the `endfloat` package defers `longtable` environments (`\DeclareDelayedFloatFlavor*{longtable}{table}`).

+The BibTeX block in the citation appendix sits in the same `code-copy-outer-scaffold` wrapper as other code blocks, so the copy button is positioned inside the block and its icon shows on hover (#13669).
