Make buscar pip installable

[axiomcura]

It’s time to make buscar pip-installable.

Before removing the analysis notebooks and restructuring the repository, I need to ensure that the package can be properly installed via pip.

Tasks to complete:

• Verify that all dependencies are correctly specified and compatible.
• Confirm that the poetry configuration is properly set up and determine whether any adjustments are needed.
• Decide which PyPI account will be used to publish the package.
• Develop unit tests to ensure that all functions behave as expected (initially using synthetic data; later, we can replace these with real profiling data).
• Remove the analysis notebooks and migrate them to a separate repository.
• Perform installation tests (e.g., fresh virtual environment, pip install, import checks) to confirm everything works as intended.
