Feature: Multi-Provider Reasoning (OpenAI, Anthropic, Local)

[cybaea]

🎯 Goal

Provide freedom of choice by allowing the Research Agent and tool-use capabilities to run on any model provider, not just Gemini.

📋 Implementation Plan

• Abstraction Layer: Refactor GeminiService into a generic ModelService interface.
• Provider Implementation:
  • Add support for OpenAI API (GPT-4o).
  • Add support for Anthropic API (Claude 3.5 Sonnet).
  • Add support for local open-weights models (via standard OpenAI-compatible endpoints).
• Tooling Compatibility: Ensure the "Computational Solver" and "Research" tools work consistently across different provider function-calling schemas.

⚙️ Design Notes

• UI should clearly distinguish between "Smart Routing" (automatic) and "Manual Override" (user-forced provider).

I came here looking for alternate provider support. I currently use:

• Kilo Gateway
• Ollama Cloud
  I'd love to see support added for these.
