Overview

Drop-in Rust reimplementation of Performance/StringInclude (rubocop-performance 1.26.1).

Rust replicates the stock pattern union in document order (regexp argument first, then regexp receiver; !~ and &. only match on the argument side) and the Util::LITERAL_REGEX literal-only gate over the raw pattern source. The wrapper rebuilds the replacement exactly like stock — with RuboCop's own interpret_string_escapes and to_string_literal helpers (available through RuboCop::Cop::Base -> include Util) — so escape interpretation and quote selection cannot drift from stock byte behavior.

Config-less: nothing to pack (the shared segment only carries the department enable flag for this cop).
