security: remove .claude/ directory from git tracking

[realityinspector]

Problem

.claude/settings.local 2.json is tracked in git. It contains AI tool configuration with commit messages including "Generated with [Claude Code]" and "Co-Authored-By: Claude" embedded in bash allow-lists.

Fix

1. Add .claude/ to .gitignore
2. Remove .claude/ from git tracking: git rm -r --cached .claude/
3. Commit the removal
