feat: AI integration for schema analysis, chart recommendation and query explaination

[Yashh56]

This pull request introduces a new, modular AI integration layer for the bridge, adding support for multiple AI providers and a set of reusable prompt templates for database schema analysis, SQL query explanation, and chart recommendation. The main changes include the implementation of provider adapters for Anthropic, Gemini, Mistral, Ollama, and Groq, the creation of prompt builders and parsers, and updates to the build process and documentation to support these features.

AI Provider Integrations

• Added new provider adapters implementing the AIProvider interface for Anthropic (anthropic.provider.ts), Gemini (gemini.provider.ts), Mistral (mistral.provider.ts), Ollama (ollama.provider.ts), and Groq (groq.provider.ts). Each adapter supports schema analysis, query explanation, chart recommendation, and connection testing. [1] [2] [3] [4] [5]

Prompt Builders and Parsers

• Introduced prompt builder modules for schema analysis, query explanation, and chart recommendation, along with a shared prompt fragment file. Includes robust parsing for chart recommendations and defensive error handling. [1] [2] [3] [4]

Build and Dependency Updates

• Updated package.json to add dependencies for all supported AI providers and new build scripts for bundled packaging, ensuring external native modules are handled correctly.

Documentation

• Added a comprehensive README to the src/ai folder, explaining the architecture, layout, and guidelines for adding new providers or prompt templates.

These changes collectively establish a flexible, extensible AI framework for the bridge, enabling advanced database assistance features and easy future expansion.
