fix: remove auto-claude framework files from version control (qa-requested)

Removed framework metadata files that should not be version controlled:
- .auto-claude-security.json
- .auto-claude-status
- .claude_settings.json

Updated .gitignore to exclude these files pattern-wide.

Files removed from git tracking but preserved on disk.
