feat: add OpenWeather plugin

[kylebuildsstuff]

Risks

Low - This is an additive change that introduces a new plugin without modifying existing functionality. The main risks are:

• Rate limiting from OpenWeather API (1000 free API calls per day)
• Potential timeout issues when the API is slow

Background

What does this PR do?

• Adds a new OpenWeather plugin for weather checking
• Implements a GET_CURRENT_WEATHER action that fetches the current weather for a specified city
• Provides TypeScript types and interfaces for OpenWeather weather API responses
• Includes environment validation for API key configuration
• Adds error handling for API calls

What kind of change is this?

Features (non-breaking change which adds functionality):

• New plugin implementation
• New TypeScript types and validation

Why are we doing this? Any context or related work?

I thought it would be neat to create agents that can fetch the weather.

Documentation changes needed?

My changes require a change to the project documentation:

• Add OpenWeather plugin setup instructions
• Document required API key configuration
• Add usage examples for weather checking
• Update plugin list in main documentation
• Add #/rate limit considerations

Testing

Where should a reviewer start?

• Review the plugin implementation in plugin-openweather/src/
• Check the main action implementation in actions/getCurrentWeather.ts
• Verify API service in service.ts
• Review type definitions in types.ts
• Check template handling in template.ts

Detailed testing steps

1. Set up environment:

OPEN_WEATHER_API_KEY=your_api_key

2. Run agent locally and test natural language queries:

• "What's the current weather in Toronto?"
• "What's the weather like in Paris?"
• "What's the weather like?"

3. Verify error handling:

• Try with invalid cities
• Test API timeout scenarios
• Check rate limit handling
