chore(lint): add Ruby linter scripts and apply rules

Adds scripts/lint with linters for mod.rs naming, contiguous use blocks,
use-as aliasing, sorted Cargo dependencies, std::collections maps, and
workspace dependency requirements. Renames mod.rs files, reorders use
statements, drops unnecessary import aliases, and sorts Cargo.toml
entries to satisfy the new rules.
