refactor(clippy): apply all super pedantic lints

Realised that I hadn't turned on super pedantic mode for clippy in the
komorebi-core and komorebic crates. This commit ensures the same clippy
config across all crates and applies the lint suggestions that arose as
a result of turning on the same config everywhere.
