Hardcoded "Open in..." app list in Files panel doesn't respect OS default app

In the Claude desktop app's Files side panel, right-clicking a file shows a context menu with "Open in Explorer" and "Open in VS Code" as the only options.

This list appears to be hardcoded and does not reflect the user's actual OS-level default application for that file type. For example, I have Typora set as the Windows default app for .md files, but Typora does not appear in this context menu at all.

This is a problem for users who don't use VS Code as their editor — the current options assume every user either wants raw Explorer or has VS Code installed, which isn't a safe assumption (e.g., writers, teachers, and non-developers using Claude for document-heavy workflows often use dedicated Markdown editors like Typora, Obsidian, etc.).

Suggestion: Either (a) add an "Open with default app" option that respects the OS file association, or (b) let users configure/add their own "Open in..." entries.
