feat: add --config option to read host.yaml for deploy

[zhaoshanren8808-ship-it]

Summary

Add --config/-c option to co deploy command to support reading host.yaml configuration file for seamless deployment.

Changes

1. Add --config option to deploy command in main.py

   • Default config file: host.yaml
   • Can be overridden with --config or -c flag

2. Add host.yaml parsing in deploy_commands.py

   • New _load_host_config() function to parse YAML
   • Supports reading entrypoint from host.yaml
   • Graceful fallback if YAML parsing fails

3. Dependencies

   • pyyaml>=6.0.0 already in dependencies

Usage

# Use default host.yaml
co deploy

# Use custom config file
co deploy --config my-config.yaml
co deploy -c prod.yaml

host.yaml Example

entrypoint: app.py
summary: My AI Agent
port: 8000

Testing

• Tested with valid host.yaml
• Tested with missing host.yaml (graceful fallback)
• Tested with invalid YAML (error handling)

Closes #80
