refactor(query): deepen runtime context/native adapter/output seams (#3076)

* refactor(query): deepen runtime context, native adapter, and cli output seams

* chore(changeset): add fragment for query seam deepening continuation

* refactor(query): converge internal command-resolution imports on canonical seam

* refactor(query): remove dead seam wrappers and converge on canonical modules

* docs(architecture): update context and adr for query seam completion

* fix(query): preserve gsd-tools stderr in cli output and clarify static ws test scope

* test(query): cover whitespace stderr and null exitCode fallback
