config to invert status polarity (punish mode)

cargo-vibe rewards success, but i've gotten a ton of people asking for "punish failure" -- could be a good First Issue for someone https://github.com/Shadlock0133/cargo-vibe/blob/a54d87b080ff7d8b3207f83f8f434b226572f0fe/src/main.rs#L106 (getting a lot of questions about this today, so leaving some notes for people wandering by)
