A new console sample that walks an `ArgumentParser`'s schema: - `GetArgumentCases()` enumerates each case's `ArgumentCaseInfo` - `GetSubCommandParsers()` returns the untyped child parsers - `IArgumentParserVisitor<'R>` recovers the typed parser when only the untyped base is in scope The sample defines a minimal git-style schema (commit, push) and prints the full case metadata at every nesting level, then prints the generated help text for comparison. Wired into Argu.sln under the `samples` folder alongside Argu.Samples.LS.

Summary
A new console sample under
samples/Argu.Samples.Introspect/that walks anArgumentParser's schema:GetArgumentCases()enumerates each case'sArgumentCaseInfo.GetSubCommandParsers()returns the untyped child parsers.IArgumentParserVisitor<'R>recovers the typed parser when only the untyped base is in scope.The sample defines a minimal git-style schema (commit, push), prints every case at every nesting level, then prints the generated help text for comparison.
Why
There's no in-repo example showing how to walk a parser's schema. The pieces are documented individually but the assembly is left to the user.
