gsxdsm c468c161c2 FN-7141: add chat context token budget indicator ...

Add a desktop Direct-chat header indicator for estimated tokens used against the active model context window.

- Estimate chat token usage client-side, including streaming text, and format compact counts.
- Render the context-window badge only for non-mobile Direct-chat threads with known model context windows.
- Cover desktop, mobile, floating-narrow, rooms, unknown-context, and streaming surfaces with tests.
- Document the dashboard behavior and add a release changeset.
