[Desktop] Routines section in Code tab sidebar is hidden and cannot be turned back on

Environment

• Claude Desktop for Windows (Microsoft Store build 2.37337.1.0), Windows 11
• Code tab

What happened
Until yesterday the Code tab sidebar showed a Routines section. Today it is gone. The routines themselves still exist and run normally; they are all listed on the "Scheduled" page.

The app's config (%APPDATA%\Claude\claude_desktop_config.json) has the built-in Routines section stored as hidden:

{
  "id": "routines",
  "kind": "routines",
  "v": 2,
  "order": 1,
  "collapsed": true,
  "shown": false
}

There is no way to turn it back on

• The right-click menu on a sidebar section header only has: New session, Edit environment, Move down, Reset order, Select all, Collapse all, Expand all, Archive all. No section visibility option.
• Not in the View menu, and not on the Customize page.
• "Reset order" did not bring it back.
• Restarting the app did not help.
• Editing "shown": true in the config file while the app is closed does not stick: on launch the app writes "shown": false back, so the value seems to come from another store.

Expected
A menu option to show the Routines section again (or have it shown by default), and a note on how to restore it today.
