git-config — Git's configuration system: parsing, serialization, value typing, and conditional includes.
This crate owns the [GitConfig] document model ([ConfigSection] /
[ConfigEntry]), the character-level parser that mirrors git's
git_parse_source, the canonical writer, the typed value accessors
([parse_config_bool], [parse_config_int], [parse_config_bool_or_int]),
and the include/includeIf resolution machinery
([load_config_with_includes], [ConfigIncludeContext]).
