Overview

Drop-in Rust reimplementation of ‘Layout/AssignmentIndentation`.

Rust walks the AST once and, for each assignment / setter call whose operator is on a different line from the RHS, computes the RHS’s expected display column (‘leftmost_multiple_assignment.display_column + IndentationWidth`). Misaligned RHSes that begin their own line emit a `[rhs_start, rhs_end, column_delta]` record, which the wrapper turns into an offense at the RHS range. Autocorrect re-locates the matching `Parser::AST::Node` by `rhs_start` and hands it to stock’s ‘AlignmentCorrector#correct` with the same `column_delta` (this keeps the heredoc / string-literal taboo handling identical to stock).

‘IndentationWidth` falls back to `Layout/IndentationWidth.Width`, then to 2 — exactly stock’s ‘configured_indentation_width`.
