fix: use forward slashes in JSON output and add size==0 guard 

- Remove forward-to-backslash conversion in JSON keys — forward slashes
  are native macOS paths and don't need JSON escaping (backslash paths
  like \b would be misinterpreted as escape sequences by JSON parsers)
- Add size==0 guard after mach_vm_region to prevent infinite loop
