Add MiniMax M3 model support

[ImBIOS]

Feature Request: MiniMax M3 Model Support

Description

Add support for MiniMax M3 models to the codebase. Currently, forgecode supports MiniMax M2 and M2.1 models but lacks M3 support.

Current Status

• ✅ MiniMax M2 - supported
• ✅ MiniMax M2.1 - supported
• ❌ MiniMax M3 - not supported

Implementation Requirements

1. Transformer Update (crates/forge_app/src/dto/openai/transformers/minimax.rs):

   • Extend the model matching logic to include minimax-m3 pattern
   • Set appropriate default parameters (temperature: 1.0, top_p: 0.95, top_k: 40)

2. Provider Configuration (crates/forge_repo/src/provider/provider.json):

   • Add MiniMax M3 models with proper context length and capabilities

3. Provider ID (crates/forge_domain/src/provider.rs):

   • Consider adding MINIMAX_M3 provider constant if needed

Example Model Specs (TBD - please verify with MiniMax API docs)

• minimax-m3 - Flagship model with extended context
