ReDock 0.4.7

• Fixed: Gemini can now finish real, multi-step work. Google's newer models attach
  a hidden token to every tool call and require it back on the next step; ReDock
  was dropping it, so Gemini tasks failed right after the first action. It is now
  carried through the whole conversation — verified against Google with a live
  two-turn run.
• New: a "Test it" button on every AI provider. One click sends a real request
  (and a real tool round-trip) through the app itself and tells you in plain
  words whether that provider works right now — no more finding out mid-task.
• Better: when a provider fails, you get one plain sentence about what happened
  and what to do — "the model is busy right now, try again" reads very
  differently from a wall of raw error text. The provider's exact words are
  still there behind a click for anyone who wants them.
• Better: setting up a provider is one visible path — pick it, add the key,
  choose a model, test it — and the model list no longer reloads every time you
  open the picker.
• Changed: the GPT suggestion now leads with OpenAI's newest low-cost model.
• Under the hood: the groundwork for ReDock on Windows is complete — the whole
  codebase now compiles for Windows, checked on every future change. Nothing
  changes on your Mac.
