fix: slow CLI start up time

[aeneasr]

Found a deeply nested dependency which was importing https://github.com/markbates/pkger, causing unreasonable CPU consumption and significant delay at start up time. With this patch, start up time was reduced from almost 3 seconds to 0.03 seconds for cold starts and 0.00s for hot starts.

$ time cli

$ time ./cli-patch

$ time ./cli-patch
