📚 Description

this aligns the telemetry cli with rest of nuxt ecosystem, also potentially reducing dependencies (mri is dropped)

it also supports more config formats (.mjs and .config dir), though we might consider using c12 in future (what do you think @pi0?)

left 2 comments otherwise nice works ❤️

also agree about migrating to c12 btw it reduces complexity with no cost
