:sparkles: Command verbosity.

[jortel]

Add command reporting verbosity. This is intended to better support troubleshooting. Mainly, the support for level=LiveOutput. This streams command output to the task activity log. Output may be filtered at 2 points:

• When the bytes are collected. Example: format output with terminal control characters (no \n).
• When the lines are reported. Filter in/out to reduce noise. Example: verbose output designed to convey progress can be interpreted and reported as progress rather than spamming the log.

The output reporting is rate-limited using a backoff algorithm.

Add command New constructor and update the repository package to use it.
