plugin-bittensor: test coverage and config

[ai16z-demirix]

Is your feature request related to a problem? Please describe.

The plugin-bittensor package currently lacks comprehensive test coverage, which poses potential risks for future maintenance and reliability. Without proper test coverage, there is an increased likelihood of introducing bugs during updates or modifications. Additionally, the absence of tests makes it challenging to verify the correct functionality of critical features such as image analysis and fact extraction, which are core components of this plugin.

Describe the solution you'd like

A comprehensive test suite should be implemented for the plugin-bittensor package. The testing implementation is expected to be divided into two main components:

1. Image Analysis Testing (sn34.ts):
   • Tests should be written to validate image URL processing and API credential handling
   • Action properties validation is expected to be implemented
   • Coverage should include both analyzeImage and analysisHistory actions
   • Mock implementations should be created for external API calls
2. Fact Evaluator Testing (fact.ts):
   • Validation logic should be thoroughly tested
   • Evaluator properties verification is expected to be implemented
   • Fact extraction functionality should be tested with various input scenarios
   • Memory management operations should be properly mocked
     The implementation should utilize vitest as the testing framework, and all tests should be organized in a tests directory structure. A vitest configuration file should be created to ensure proper test environment setup. The test coverage is expected to achieve a high percentage, focusing on both successful scenarios and error handling cases.
     Dependencies should be properly mocked to ensure isolated testing, and the testing structure should follow the established patterns used in other plugins within the ecosystem. This approach is expected to enhance code reliability and make future maintenance more manageable.
