Merge origin/dev (readback overhaul c6d22e6e) into default-texture-objects - true per-target default texture objects supersede the readback branch texture-0 silent no-ops: removed the null-slot early-outs in TexImage1D/2D/3D(Multisample) and TexBuffer plus the DefaultTextureOperationsAreSilentNoOps test so name-0 operations actually (re)specify the default objects; deduped the shared state-reset fixes, keeping upstream std::clamp for GL_MAX_UNIFORM_BUFFER_BINDINGS, the Int-typed ActiveTexture combined-units range check, renderbuffer name-0 unbind, and vertex-attrib-0 current-value writes with the attrib-0 round-trip test
