Remove `__pycache__` and `*credx_ai.egg-info` and add to `.gitignore`

[ParagEkbote]

Why This Is Important

• Clean Repository: Prevents unnecessary build artifacts and cache files from cluttering version control.
• Efficiency: Reduces repository size and avoids committing files that change frequently and have no value in source control.
• Best Practices: Aligns with Python community standards for ignoring generated files.

---

Tasks

• Delete existing __pycache__ directories and *.egg-info files from the repository.
• Add entries to .gitignore for:
  • __pycache__/
  • *.egg-info/
• Verify that these files are excluded from future commits.
• Update documentation (if applicable) to note that these files are ignored.
• Communicate the cleanup to contributors.

---

Acceptance Criteria

• All __pycache__ and *.egg-info files are removed from the repository history (or at least from the working tree).
• .gitignore contains rules to exclude __pycache__/ and *.egg-info/.
• Running git status after changes shows no tracked __pycache__ or *.egg-info files.
• Contributors confirm that these files are no longer committed accidentally.
