feat: add Google Gemini provider with CLI token reuse support

- Add src/providers/gemini.rs with support for:
  - Direct API key (GEMINI_API_KEY env var or config)
  - Gemini CLI OAuth token reuse (~/.gemini/oauth_creds.json)
  - GOOGLE_API_KEY environment variable fallback
- Register gemini provider in src/providers/mod.rs with aliases: gemini, google, google-gemini
- Add Gemini to onboarding wizard with:
  - Auto-detection of existing Gemini CLI credentials
  - Model selection (gemini-2.0-flash, gemini-1.5-pro, etc.)
  - API key URL and env var guidance
- Add comprehensive tests for Gemini provider
- Fix pre-existing clippy warnings in email_channel.rs and whatsapp.rs
