[ftnext]

Link to Issue or Description of Change

1. Link to an existing issue (if applicable):

N/A - This is a minor style fix.

2. Or, if no issue exists, describe the change:

Problem:
Files under contributing/samples/gepa/ do not conform to the project's autoformat style.
Running ./autoformat.sh modifies these files, which means they were not properly formatted.

Solution:
Apply isort and pyink formatting by running ./autoformat.sh.
This removes extra blank lines between third-party imports and local imports in:

• contributing/samples/gepa/experiment.py
• contributing/samples/gepa/run_experiment.py

Testing Plan

This is a small style fix (similar to typo fixes), so detailed testing is not required.

Unit Tests:

• No unit test changes needed - style-only change.
• All unit tests pass locally (no functional changes).

Manual End-to-End (E2E) Tests:

N/A - No functional changes. Verified by running ./autoformat.sh again with no further modifications.

Checklist

• I have read the CONTRIBUTING.md document.
• I have performed a self-review of my own code.
• I have commented my code, particularly in hard-to-understand areas. (N/A - no logic changes)
• I have added tests that prove my fix is effective or that my feature works. (N/A - style-only)
• New and existing unit tests pass locally with my changes.
• I have manually tested my changes end-to-end. (N/A - style-only)
• Any dependent changes have been merged and published in downstream modules. (N/A)

Additional context

This ensures that contributing/samples/gepa/ files follow the same formatting standards as the rest of the codebase.
