Overview

Base-aware, source-preserving provider for native top-level Bash owners. Functions and assignments have stable AST identities. Every other top-level form must remain identical across all revisions in a composite. rubocop:disable Metrics/AbcSize, Metrics/ClassLength, Metrics/CyclomaticComplexity, Metrics/MethodLength, Metrics/ParameterLists, Metrics/PerceivedComplexity -- provider decisions, source plans, and verification form one boundary
