[Bug]: "Open in VS Code" is offered on iPad and phone browsers, where it can never open #27544

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. Run T3 Code on a Mac that advertises an SSH route (sshd running, or Tailscale SSH).
2. Connect to it from the web client on an iPad (not the native iOS app).
3. Open a thread and tap "Open in VS Code".

Expected behavior

On iOS and Android browsers, the menu does not offer desktop editors and says why they are unavailable. Browsers on computers behave as they do today.

Actual behavior

Safari shows "Safari no puede abrir la página porque la dirección no es válida" ("Safari cannot open the page because the address is invalid"). This happens with Tailscale on and off.

From reading apps/web/src/remoteOpen.ts at 32ecd71726:

• remoteCapableEditorsAtom falls back to REMOTE_FALLBACK_EDITORS = ["vscode"] when there is no desktop bridge to probe, so a browser always offers VS Code.
• The button and the keyboard shortcut both use that list, and build a vscode://vscode-remote/ssh-remote+… URL. iPadOS has no desktop VS Code to handle it.
• openRemoteEditorUrl calls window.location.assign(url) and returns true, so the failure is never detected.

I reproduced this on an iPad only. Android is included because it has no desktop editors either, but I have not tested it.

Related work on the same list:

• fix(web): show remote editors without changing the VS Code default #25490, fix(web): show supported remote editors in the picker #23572 and fix(web): let browsers pick VSCodium, Cursor or Zed for remote open #11209 widen what browsers are offered. None of them excludes iOS or Android, so merging one as is would add more entries that fail the same way on these devices.
• Browser client can't choose a remote editor: picker only offers VS Code, and VSCodium/Zed/others are missing #27510 and Let the browser client choose a remote editor (VSCodium, Zed, etc.), not just VS Code #27518 ask for the same wider list for computers. That request is complementary: it fits as long as phones and tablets stay out of the list.
