This release introduces experimental support for custom instruction files, allowing users to provide more detailed context and guidelines for AI analysis of their projects.

## What's New

### Custom Instruction File Support (#40, #46)

- Added `output.instructionFilePath` option to configuration
  - Updated output generators to include project instructions in the output

We are introducing this feature experimentally and plan to continuously evaluate and improve it based on user feedback and real-world usage. Your insights and experiences with this new feature will be invaluable as we refine and enhance it in future updates.

Note: Custom instructions are appended at the end of the output file for optimal AI processing
