2.0.2

Two rounds of bug fixes since 2.0.1, plus clearer feedback when connecting a provider.

Provider setup

• You can now tell when a provider actually connected. The Setup Provider modal has no
  submit button — credentials autosave and the provider commits itself once validation
  passes — so a successful setup looked identical to an untouched form. The only signal was
  a small check in the title bar, easy to miss and in some cases not rendered at all. There
  is now a connection status row in the modal itself (checking / connected / the actual
  error message) and an explicit Done button. This was especially confusing during
  onboarding, where nothing told you the provider had been added or that you could close the
  dialog. (#461)
• Providers configured with a stored API-key secret previously got no in-modal confirmation
  at all — the old success styling only ever applied to plain text fields. (#461)
• Fixed a race where finishing setup could leave the provider's ID and its displayed name
  disagreeing, or report a spurious "Provider not found" on a provider that had connected
  fine. (#463)

Fixes

• Popout windows: timers and DOM globals are now scoped to the correct window, so features
  used in a popped-out pane behave the same as in the main window. (#462)
• Assorted correctness fixes across chat, graph, search, and the vector store found during a
  review pass. (#462)
