Fix macOS extended attributes error in Docker container operations (#19)

Improve tar commands to properly exclude extended attributes on macOS that cause
"lsetxattr com.apple.provenance" errors in Docker operations. This extends the
previous fix to cover additional tar operations in the container setup process.

Changes:
- Add explicit --no-xattrs and --no-fflags flags for macOS tar operations
- Apply fix to both git history copying and Claude config directory copying
- Auto-fix ESLint style issues for consistency
