feat(gemini): update Gemini model types and implement rate limiting for free tier

- Changed Gemini model types to 'gemini-2.5-flash-lite', 'gemini-2.5-flash', and 'gemini-3-flash'.
- Introduced RPM limits for free tier models with a maximum of 10 RPM for 'gemini-2.5-flash-lite' and 5 RPM for the others.
- Added rate limiting enforcement in the GeminiAgent class, which waits based on the model's RPM limit.
- Updated getGeminiConfig to include billingEnabled setting, allowing users to skip rate limiting if billing is enabled.
- Modified ContextSettingsModal to reflect new model options and added a toggle for enabling billing.
- Updated default settings to use the new model and billing configuration.

Claude-mem supports Google's Gemini API as an alternative to the Claude Agent SDK for extracting observations from your sessions. This can significantly reduce costs since Gemini offers a generous free tier.
<Note>
**Free Tier Available**: Google provides 60 requests per minute and 1 million tokens per month at no cost. No billing information required.
</Note>
<Warning>
**Free Tier Rate Limits**: Without billing enabled, Gemini has strict rate limits (5-10 RPM). Enable billing on your Google Cloud project to unlock 1000-4000 RPM while still using the free quota.

Billing information is generally not required to use the free tier.
**No billing required** to get started, but we recommend enabling billing to unlock higher rate limits (1000-4000 RPM vs 5-10 RPM) while still using the free quota.

### Rate Limiting
The free tier allows 60 requests per minute. If you hit rate limits:
Google has two rate limit tiers for free usage:
**Without billing (API key only):**
| Model | RPM | TPM |
|-------|-----|-----|
| gemini-2.5-flash-lite | 10 | 250K |
| gemini-2.5-flash | 5 | 250K |
| gemini-3-flash | 5 | 250K |
Claude-mem enforces these limits automatically with built-in delays between requests. Processing may be slower but stays within limits.
**With billing enabled (still free tier):**
| Model | RPM | TPM |
|-------|-----|-----|
| gemini-2.5-flash-lite | 4,000 | 4M |
| gemini-2.5-flash | 1,000 | 1M |
| gemini-3-flash | 1,000 | 1M |
<Tip>
**Recommended**: Enable billing on your Google Cloud project to unlock much higher rate limits. You won't be charged unless you exceed the generous free quota. This allows claude-mem to process observations instantly instead of waiting between requests.
</Tip>
If you hit rate limits:
- Claude-mem automatically falls back to Claude SDK
- Consider upgrading to a paid Gemini plan for higher limits
- Or switch back to Claude as your primary provider
