Create extdeps/gpu/types.dag; add MemoryKind/MemoryFacts to extdeps/memory/types.dag

[gunbai-bot]

Summary

• Add dsl/extdeps/gpu/types.dag with GpuFacts, AcceleratorFacts, and supporting GPU capability types (GpuComputeCapability, GpuRuntime, gpu_compute_capability_sm_label) relocated from product.compute_fabric.
• Add MemoryKind and MemoryFacts to dsl/extdeps/memory/types.dag as the single-authority home for memory fact vocabulary.

These are the extdeps authority homes for compute_fabric vocabulary relocation; consumers can migrate imports in follow-on work.

Test plan

• gunbc compile --source-root dsl --target rust — no errors in new/modified modules
• Parent session wires compute_fabric and witness imports to the new extdeps homes

Review response (parallel definitions)

Finding verified: GpuRuntime, GpuComputeCapability, GpuCapabilityLabelOutcome, gpu_compute_capability_sm_label, GpuFacts, AcceleratorFacts, MemoryKind, and MemoryFacts still exist in product.compute_fabric.dag alongside the new extdeps homes.

Why not option (a) in this PR: Parent manager scope (vivid-wren-440, serial hub migration) explicitly forbids touching compute_fabric.dag or any hub file from this leaf PR. Deleting the compute_fabric copies here would conflict with the in-flight hub serial PR and the final connector PR that re-models compute_fabric as the thin need↔opportunity connector.

Fix applied — option (b): Added named SCAFFOLD + dissolve-on: debt carriers:

• gpu_types_compute_fabric_parallel_copy_debt in dsl/extdeps/gpu/types.dag
• memory_types_compute_fabric_parallel_copy_debt in dsl/extdeps/memory/types.dag

Both name the bounded trigger: product.compute_fabric connector PR deletes local copies and imports from extdeps.

Consumer migration in this PR: extdeps_round2_grounding_witness_test.dag already repointed to the extdeps homes (one witness consumer; hub files remain on compute_fabric imports until the hub serial PR).

gpu_compute_capability_sm_label dispatch: Copied verbatim from the existing compute_fabric shape (not a new fork). Vendor-table dissolution is separate debt; this PR does not harden a new pattern.
