Capture the Omega public demo

Omega has an explicitly opt-in public demo mode for capturing a real product workroom without exposing normal user state. The mode stages three visible surfaces together:

• the fictional Orbit Notes project tree;
• src/commandPalette.ts in the editor;
• the Sarah workroom pane with a fictional conversation and activity history.

Run the normal development build and launch path:

script/omega-public-demo

The script creates a fresh temporary profile, prints its location, builds Omega with the repository's regular release-fast profile, and launches the checked-in fixture. To use an already-built binary:

OMEGA_DEMO_BINARY=/absolute/path/to/omega script/omega-public-demo

The underlying application invocation is:

omega \
  --demo-workroom \
  --user-data-dir /a/fresh/dedicated/profile \
  /path/to/omega/assets/demo-workroom \
  /path/to/omega/assets/demo-workroom/src/commandPalette.ts

--demo-workroom is rejected unless --user-data-dir is also present. In demo mode the workroom uses a fixed in-memory projection, does not initialize its live supervisor or account binding, and cannot send messages. The fixture contains no credentials, real accounts, private paths, or real customer data. Normal launches never enable the projection.

For a homepage capture, use a clean 1600×1000 window (or the requested matching 16:10 export size), keep the left project dock and right Sarah dock open, and make sure src/commandPalette.ts is the active editor tab. Hide unrelated desktop notifications and crop only to the Omega window. The visible PUBLIC DEMO label is intentional provenance.

Before publishing, verify:

1. The title bar identifies Omega.
2. Orbit Notes, commandPalette.ts, and the Sarah pane are visible at once.
3. The workroom says PUBLIC DEMO and fictional data.
4. No home-directory segment, account name, notification, or unrelated project is visible.
