veguAI f5d41c04c8 0.37.0 (#267)
0.37.0

- **Director Planning** — Multi-step todo lists in director chat plus a Generate long progress action for multi-beat scene arcs.
- **Auto Narration** — Unified auto-narration replacing the old Narrate after Dialogue toggle, with a chance slider and weighted action mix.
- **LLM Prompt Templates Manager** — Dedicated UI tab for viewing, creating, editing, and deleting prompt templates.
- **Character Folders** — Collapsible folders in the World Editor character list, synced across linked scenes.
- **OpenAI Compatible TTS** — Connect any number of OpenAI-compatible TTS servers in parallel.
- **KoboldCpp TTS Auto-Setup** — KoboldCpp clients with a TTS model loaded register themselves as a TTS backend.
- **Model Testing Harness** — Bundled scene that runs basic capability tests against any connected LLM.

Plus 27 improvements and 28 bug fixes
