v0.9.8 — Model selection: dynamic chat model + recognition model & language

Added

• Recognition model & language picker (Settings → Dictation, cloud engine): choose Turbo
  (faster) or Large v3 (more accurate), and force a recognition language (Auto / Russian /
  English) — forcing helps short phrases that auto-detect gets wrong. The local engine (GigaAM)
  is Russian-only and ignores these. History records the model actually used.

Changed

• The AI term-fixing model is no longer hard-coded. The app now fetches the live model list
  with your key (GET /v1/models), filters chat-capable models, and picks the best available
  by a priority chain (llama-3.3-70b-versatile → openai/gpt-oss-120b → openai/gpt-oss-20b
  → llama-3.1-8b-instant → gemma2-9b-it), falling back to the first available.
• Vocabulary settings gained an AI model picker: “Recommended (automatic)” by default, with
  the full live list for power users. Visible only when AI term-fixing is on.

Fixed

• Self-healing: if Groq removes or renames the selected model (as with qwen/qwen3-32b in
  0.9.3, which returned 404), the app now switches to the recommended model on its own — no
  urgent release needed. A stale saved choice migrates to “automatic”, and a 404 during dictation
  triggers a background re-resolve so the next dictation uses a live model. Dictation stays
  fail-open throughout.
