Desktop app: no discoverable way to switch project/working folder for a new session

Switching the working folder for a new Code session is buried and inconsistent:

• The "Code" tab sidebar (New session / Artifacts / Customize / Recents) has no project switcher at all — it's implicitly locked to whatever folder was last used.
• "Home -> Projects" looks like the natural place to switch, but it's a separate concept ("Projects" as saved entities) that doesn't list folders you've simply run sessions against, and offers no link back to the Code workspace.
• The actual working-folder picker for a new session turns out to be a small unlabeled pill (e.g. "manga_translator") at the bottom of the "Welcome back" screen, next to "Local" — easy to miss, not visually distinguished as an interactive folder selector.

Suggestion: Put one clearly-labeled "Project/Folder" switcher in a consistent location (e.g. top bar), used by both the Code tab and the session-start screen, so users don't have to discover the bottom pill by trial and error.
