Add Claude (Anthropic) as a provider

[thunder-velvet]

Overview

This issue proposes adding Anthropic's Claude models as a new AI provider in AgentHeroes.

Why Claude?

Claude offers several competitive advantages that would benefit our users:

• State-of-the-art language model capabilities, particularly with Claude 3 Opus and Sonnet
• Longer context windows (up to 200k tokens)
• Strong reasoning and coding capabilities
• Different pricing model than OpenAI (potentially more cost-effective for certain use cases)
• Diversifies our AI provider options, giving users more choices

Implementation

Similar to how we've implemented the OpenAI provider, we would need to:

1. Add CLAUDE to the GenerationIdentifiers enum
2. Create a new claude.provider.ts file implementing the GenerationBase class
3. Support Claude's main models (Claude 3 Opus, Claude 3 Sonnet, Claude 3 Haiku)
4. Add Claude to the providersList in providers.list.ts

API Details

Claude can be accessed through Anthropic's API:

• API Documentation: https://docs.anthropic.com/claude/reference/
• It uses a similar REST-based API structure to OpenAI
• Would require users to supply their own Anthropic API key

Dependencies

We would need to add the Anthropic SDK to our project:

@anthropic-ai/sdk

Questions

• Should we support Claude's vision capabilities?
• Do we want to enable the tool use features?
• Should we add support for Claude's system prompt feature?
