[feature] Configurable CLI foreground colors for task names in moon.yml

[k0pernikus]

Moon assigns random colors to tasks during execution. While acceptable, it frequently selects semantic colors like red or orange that indicate errors or warnings in terminal environments.

In my setup, these colors are reserved strictly for failures. Seeing them assigned to standard task execution creates unnecessary cognitive friction.

Additionally, grouping related tasks by color would significantly improve readability. For example, :test-chrome and :test-firefox are logically related and should ideally share the same output color.

Ideally, this would be configurable directly within moon.yml:

  test-chrome:
    extends: base_browser_test
    cli:
      title-fg-color: cyan
    args:
      - --browser
      - chromium

Alternatively, it would suffice to provide an option to globally restrict the task runner's color pool, preventing semantic color collisions by explicitly blacklisting red, orange, and green from the randomizer.
