  1. chore: Document return behavior of cdk diff 

    The `cdk diff` command intentionally returns non-zero when a difference is found,
similar to how the POSIX `diff` command behaves (returning 0 when no difference is
found, 1 when some difference is found, and >1 when an error occurred). This
behavior was however undocumented, possibly leading to user confusion.

This change adds a note in `cdk --help` that mentions the exit code 1 will be used
when a difference is found.
