Pull request overview

This pull request refactors the build system to use justfile as the primary command runner, moving native library build logic from bash scripts in justfile into sbt tasks. The refactoring aims to consolidate build logic and provide a cleaner interface through just commands.

Changes:

• Moved native library generation logic from justfile bash script to sbt tasks in NativeBuildSettings.scala
• Added utility functions in Utils.scala for process execution and logging
• Created cleanHeaders command in ExtraCommands.scala
• Simplified justfile recipes to delegate to sbt commands
• Updated documentation (README.md, CONTRIBUTING.md) to reflect the new command patterns
