chore(release): prepare for 2026.2.1

[Benoît Cortier (CBenoit)]

2026.2.1 (2026-06-03)

Bug Fixes

• dgw: serve standalone web app and recording player static assets (#1811) (eb6c032627)

  The standalone web application and the recording player loaded their
  main page but failed to load any static assets (JS, CSS, fonts), which
  returned HTTP 500. As a result both UIs were effectively broken.

  Requests for sub-resources under /jet/webapp/client/ and /jet/jrec/play/
  now resolve correctly, restoring the standalone web application and the
  recording player.
