E6: remove build-tool plugin (architecturally incompatible with the monorepo-only CLI); rewrite the command plugin as a thin pass-through to swift-gtk-gen. E7: add swift-format as a dependency, format generated output in-process before writeIfChanged, re-enable swift format lint --strict in compile-gate.sh. CamelCase renderer identifiers (enum/bitfield cases, signal trampoline names, _sgtk_* helpers, __result/__ptr temporaries, hardcoded G_TYPE_* GValue constants) and drop generated block comments to reach zero lint findings across all 6 tiers.
