Subject: [PATCH] [BUGFIX] Make Gemini model configurable and update default
 model

Replace the outdated hardcoded Gemini model with a configurable setup and
set a working default model.

- Add model configuration via `geminiModel` extension setting
- Support overriding model via `GOOGLE_GEMINI_MODEL` environment variable

Resolves: #1
