Контракт
- assert default values populate when environment variables and CLI arguments are omitted
- assert environment variable fallbacks populate fields when CLI flags are absent
- assert CLI options take strict precedence over environment variables
- assert empty string environment variable for integer fails with ValueValidation instead of falling back to default
- assert empty string environment variable for Option<String> resolves to Some("") rather than None
- assert default derive bool with env uses strict bool::from_str, rejecting 1, 0, yes, and no with InvalidValue
- assert BoolishValueParser resolves truthy and falsy strings including 1, 0, yes, no, on, off to boolean values
- assert global flags propagate across subcommands while non-global options placed after subcommands fail with UnknownArgument
- assert get_flag returns false for omitted SetTrue flag and panics when called on ArgAction::Set argument
