vscode.ts: Fix close current folder

Fixes VscodeProvider to correctly obey the ew parameter.

Based on changes by @rdbeach. See the previous commit.

When you choose to close the current folder, it doesn't close properly
because the lastVisiited setting is still use. This fixes that.

feat(extensions): add helper header above extensions search

Add a short message above the search box on the Extensions panel. This
helps explain the extension divergence to the user.

If they click dismiss, it stores an item in localStorage to prevent the
message from showing up on subsequent loads.

 favicon: Add dark mode support

Closes #2538

Works as expected on latest Firefox and Chromium.

It requires git-lfs to pull down if you want to adjust the favicon and
also the affinity designer software available only on Windows and Mac.

Might be a good idea to switch to Figma at some point and commit a
.fig file.

Updates #2349

Electron doesn't support FreeBSD.

Now that we've moved to the submodule, there is no need to reset changes
in there :)

We don't have an agent for FreeBSD right now.
