less noisy change-tracker

[onur-ozkan]

Reduces noise from change-tracker by disabling change-tracker by default and displaying its help messages only in verbose mode. This means users won't see any change-tracker helper or change messages unless it is explicitly enabled in config.toml or the verbose flag is passed.

Alternative to #130356.

This should allow removing

Lines 26 to 27 in dde7d66

	change-id = 999999

, right? If so would you mind removing it in this PR?

I'm not sure about this change, as I think "human" users should be warned about changes by default

[onur-ozkan]

I think this is mostly useful for experts and we should just include this in the documentation instead of turning it on by default.
