fix: add Gemini 3.x before 2.5 retirement

+## Version 0.1.31
+
+feat - add Gemini 3.6 Flash, 3.5 Flash, 3.5 Flash Lite, 3.1 Flash Lite, and 3.1 Pro Preview model options; default to Gemini 3.6 Flash. Gemini 2.5 models retire in October 2026.
+
+fix - send Vertex AI translation requests to the `global` endpoint instead of the Cloud Functions location. Gemini 3.x is only served from the `global`, `us` and `eu` endpoints, so a single-region endpoint fails for the new default model.

 chore: remove unused rimraf dependency

+chore - switch content filter from `gemini-2.5-flash` to `gemini-3.1-flash-lite` (similar price to 2.5 Flash and better quality; 2.5 Flash retires October 2026)
+
+fix - content filter now calls Vertex at `global` via `@genkit-ai/google-genai`. `gemini-3.1-flash-lite` is not served on regional endpoints like `us-central1`, and the old `@genkit-ai/vertexai` plugin rejects `global`.
