Add clarifai model init CLI command

[Copilot]

This PR implements the clarifai model init CLI command to help users quickly scaffold new model projects with the proper directory structure and template files.

Features

The new command creates the following structure in the specified directory:

├── 1/
│   └── model.py
├── requirements.txt
└── config.yaml

Usage

# Initialize in current directory with default ModelClass
clarifai model init

# Initialize in specific path
clarifai model init /path/to/my-model

# Initialize with MCP model type
clarifai model init --model-type-id mcp

# Initialize with OpenAI model type  
clarifai model init --model-type-id openai

Model Type Support

• Default: Uses ModelClass for general-purpose models
• MCP: Uses MCPModelClass with FastMCP server template including tools, resources, and prompts
• OpenAI: Uses OpenAIModelClass for OpenAI-compatible API wrappers

Template Features

• TODO Comments: All templates include # TODO: please fill in comments for easy discovery with grep
• Latest SDK Version: requirements.txt automatically includes the current clarifai SDK version (11.4.7)
• Proper Configuration: config.yaml is pre-configured with the appropriate model_type_id
• File Protection: Won't overwrite existing files, shows warnings instead
• Comprehensive Examples: Each template includes example implementations and best practices

User Guidance

After initialization, users get clear next steps:

1. Search for TODO comments in generated files
2. Update model configuration in config.yaml
3. Add model dependencies to requirements.txt
4. Implement model logic in 1/model.py

This significantly reduces the friction for users to get started with custom Clarifai models by providing proper scaffolding and guidance.

Fixes #610.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:
