feat: Improve CLI styling output for `doctor` command

[kitten]

Summary

More commands to come, but initially, this PR lays the foundation for custom and improved CLI output and styling for the doctor command.

Other commands may prove to be a larger challenge since they may require significant blocking time (typescript-related tasks) and hence may need to happen off-thread.

Set of changes

• Create custom tty/term interface with ANSI sequences
  • Add stdin and stdout logic
• Update composition of gradual CLI output
• Update formatting of doctor command
