Visual editor outline shows Code Cell entries; quarto.symbols.showCodeCellsInOutline has no effect

Description

In the Quarto visual editor, the outline panel (Ctrl+Alt+O) lists every code block as a Code Cell entry, cluttering heading navigation in long documents. The existing setting quarto.symbols.showCodeCellsInOutline has no effect on this outline.

Environment

• Positron 1.130.0 (VS Code / Code OSS derivative) on Windows 11
• Quarto extension: 1.136.0 and 1.137.0 (both reproduce)

Steps to reproduce

1. Open a .qmd with several R/Python code cells and headings in the visual editor.
2. Press Ctrl+Alt+O to open the outline.
3. The outline shows each code cell as a Code Cell item interleaved with headings (only Metadata and heading entries are desired).
4. Set quarto.symbols.showCodeCellsInOutline: false in settings and reload. Source-mode outline obeys it; the visual-editor outline does not change.

Background

quarto.symbols.showCodeCellsInOutline (added in 1.133.0, #974) only controls the source-mode outline / workspace symbols. The visual editor's outline is implemented inside the editor webview and does not read this setting at all, so there is no user-facing way to hide code cells there.

Expected behavior

Either:

• quarto.symbols.showCodeCellsInOutline should also apply to the visual editor outline, or
• the visual editor outline should expose its own toggle and default to headings/metadata only (code cells are rarely useful as outline entries).

Local workaround (what we ship)

Filter out rmd_chunk items in the outline renderer:

o = u => {
  if (u.type === "rmd_chunk") return null;
  // ... original item rendering
}

Works, but requires patching the bundled extension file (lost on every extension upgrade).

Locate the visual editor outline renderer and compare its handling of rmd_chunk items with the source-mode implementation of quarto.symbols.showCodeCellsInOutline. Reproduce the issue with a .qmd containing headings and R or Python cells, then verify that the setting hides Code Cell entries in the visual-editor outline without removing headings or metadata.
