Overview

Drop-in Rust reimplementation of RSpec/LetSetup (rubocop-rspec 3.10.2).

Everything is computed on the shared walk: query roots are scope-change frames (example/shared groups with an rspec receiver and include_* blocks), candidates are collected lets literally named let! with one plain sym/str name, an inner let! shadowed check compares (kind, value) — let!('w') and let!(:w) do not shadow each other — and "used" means a receiverless ZERO-argument send with the same name anywhere in the root's subtree (stock's (send nil? %) search pattern has no argument wildcard, so w(1) and w(&b) are not uses while w { } is). Probed quirks live as differential specs in let_setup_edge_cases_spec.rb.
