Overview

Drop-in Rust reimplementation of Layout/SpaceBeforeFirstArg.

Rust replays stock's on_send / on_csend over prism CallNodes (parenless, non-operator, non-setter calls with arguments — a block-pass counts like in parser-gem) and the whole PrecedingFollowingAlignment scan for AllowForAlignment: nearest candidate line per direction (comments and blanks transparent), the indentation-filtered second pass, char-column aligned_words?, and the assignment-token alignment for :sym=-shaped arguments (found with a masked longest-match operator scan).

Each offense is the [start, end) whitespace run before the first argument (possibly empty for glued arguments); the corrector replaces it with a single space.
