Module git_utils 

Pure git plumbing shared across feature modules (sdd change binding, tool agents-md, skills config discovery, prompts paths).

Function bodies are moved verbatim from their original homes (sdd::change::git_native, skills::shared::git) so error messages stay byte-identical. Sdd-specific binding semantics (ChangeGitBinding, read/write_binding, start/attach/checkpoint flows) remain in sdd::change::git_native.

This module is a member of the top-level utility layer (future llman-core); it MUST NOT import feature modules (sdd/skills/tool/x).
