fix: Enhanced Template, Issue and Model Selection with Search Functionality

[gmickel]

Description

This PR introduces significant improvements to our template and model selection processes, as well as GitHub issue selection. We've replaced the simple select prompts with more powerful search functionality, providing users with a more interactive and informative selection experience. Additionally, we've added early checks for necessary environment variables to prevent unnecessary processing when API keys are missing.

Changes

1. Model Selection Enhancements

• Replaced select with search for model selection
• Implemented filtering based on user input for model names and IDs
• Added detailed model information display (context window, max output, pricing)

2. Template Selection Improvements

• Updated selectTemplatePrompt to use search instead of select
• Added template content preview in the selection interface
• Implemented template filtering based on user input

3. GitHub Issue Selection Updates

• Modified selectGitHubIssuePrompt to use search
• Added issue filtering based on title and number
• Included issue descriptions in the selection interface

4. Error Handling and Edge Cases

• Improved error handling for missing or undefined properties in GitHub issues
• Added safeguards against potential errors when reading template files
• Enhanced type checks and null/undefined handling

5. Test Updates

• Updated test files to mock search instead of select
• Added new test cases to cover error scenarios and edge cases
• Adjusted expectations to match new function signatures and behaviors
