fix(amd395): activate compatible native versions

[rjckkkkk]

Summary

• sync the compatible native engine lifecycle fix from fix(engine): activate compatible native versions #107 onto the AMD395 Linux delivery branch
• default engine ensure now reuses and activates an imported Catalog-compatible llama.cpp build
• deployment accepts verified compatible inventory and prefers the active binary
• exact installed versions still take precedence over compatible fallbacks

Validation

• go test ./... -count=1
• go vet ./...
• go test -race ./internal/engine ./internal/knowledge ./internal/hal ./cmd/aima -count=1
• Baiying AMD395: imported b9637 against Catalog b9330, default ensure reused and activated the same inventory ID, deploy launched that exact dist binary, health/chat returned HTTP 200, status reached running/ready/healthy, and isolated process/port/data were cleaned

After merge, the amd395-linux push workflow must produce the partner package from the merge commit.
