feat(gemini): implement function calling, generationConfig, and update models

- Implement function calling support (functionDeclarations, functionResponse)
- Add functionCall SSE parsing and empty stream retry support
- Add generationConfig (temperature, maxOutputTokens)
- Add thinkingConfig for Gemini 3 and thinking models
- Add toolConfig (functionCallingConfig.mode)
- Fix .expect() panics with .ok_or_else()
- Restrict oauth credentials file permissions to 0600
- Update docs and FEATURE_PARITY.md
- Update wizard to current Gemini 3.1 and 2.5 models

# LLM Provider Configuration
IronClaw defaults to NEAR AI for model access, but supports any OpenAI-compatible
endpoint as well as Anthropic and Ollama directly. This guide covers the most common
configurations.

## Google Gemini (OAuth)
Uses Google OAuth with PKCE (S256) for authentication — no API key required.
On first run, a browser opens for Google account login. Credentials (including
refresh token) are saved to `~/.gemini/oauth_creds.json` with `0600` permissions.
```env
LLM_BACKEND=gemini_oauth
GEMINI_MODEL=gemini-2.5-flash
```
### Supported features
| Feature | Status | Notes |
|---|---|---|
| Function calling | ✅ | `functionDeclarations` / `functionCall` / `functionResponse` |
| `generationConfig` | ✅ | `temperature`, `maxOutputTokens` passed from request |
| `thinkingConfig` | ✅ | `includeThoughts: true` for `gemini-3`/`thinking` models |
| `toolConfig` | ✅ | `functionCallingConfig.mode`: `AUTO`/`ANY`/`NONE` |
| SSE streaming | ✅ | Cloud Code API with `streamGenerateContent?alt=sse` |
| Token refresh | ✅ | Automatic via refresh token |
### Popular models
| Model | ID | Notes |
|---|---|---|
| Gemini 3.1 Pro | `gemini-3.1-pro-preview` | Latest, strongest reasoning |
| Gemini 3 Flash | `gemini-3-flash-preview` | Fast preview with thinkingLevel |
| Gemini 2.5 Pro | `gemini-2.5-pro` | Stable, strong reasoning |
| Gemini 2.5 Flash | `gemini-2.5-flash` | Fast, good quality |
| Gemini 2.5 Flash Lite | `gemini-2.5-flash-lite` | Fastest, lightweight |
### Cloud Code API vs standard API
Models containing `preview` or `gemini-3` in the name route through the
Cloud Code API (`cloudcode-pa.googleapis.com`) which supports SSE streaming
and project-scoped access. Other models use the standard Generative Language
API (`generativelanguage.googleapis.com`).

## Ollama (local)
Install Ollama from [ollama.com](https://ollama.com), pull a model, then:
