diagnostic messages. Defaults to 'info'.
This update enables better control over message presentation
(e.g., coloring) based on severity levels such as 'info', 'warn',
and 'error'.

Updated to process the parameter for events. Messages
are now formatted with colors based on the
(e.g., 'info', 'warn', 'error').
This change ensures diagnostic messages are visually distinct,
improving clarity and reducing debugging effort during test runs.

Enhanced  to include colors for the following
diagnostic levels:
 : blue - info
 : yellow - warn
 : red - error

Refs: nodejs#55922

Updated coverage threshold checks in to use the

'error' level for red-colored formatting.
This ensures coverage errors are highlighted effectively in the output.
