feat: Add rich log format and Go formatter

- Introduce a new protobuf text format for logs that includes structured
  tool call data (command, stdout, stderr, etc.).
- Create a new Go program, format_rich_log.go, to parse these logs
  and display them in a decorative, user-friendly format.
- Add example rich log files for testing.
