Overview

Drop-in Rust reimplementation of Layout/SpaceAroundEqualsInParameterDefault.

Rust walks the AST once and emits one [start, end] range per offending optarg — range_between(arg.end_pos, value.begin_pos), stock's offense range — computed straight from the OptionalParameterNode's name_loc / operator_loc / value positions and the two space_after? byte checks (\s at the arg-name end and at the = end). This replaces stock's processed_source.tokens_within(node) token access, the "toucher" cost, with prism-native node positions.

The wrapper reproduces stock's message (missing under space, detected under no_space) and its /=\s*(\S+)/ autocorrect verbatim on the Ruby side, so detection and autocorrect are byte-identical.
