fix(code): bind aligned native CPU source provenance

[erikleblansch]

Scope

Bind the native trial to core 6d65bb12ed7b8720d43868c9306313133a5b96ae and its reviewed Q1 aligned-load correction. Validate the atomic CPU source/compile pair, exact eight-file wrapper inventory, compiler-input verification and copied-build projections. Historical 4/6/7-file formats remain readable but cannot authorize the new trial.

Verification

• 51 targeted inert Python tests pass without skips when the retained exact core and loader sources are supplied; no native/model build or execution on the development host.
• Independent read-only review passed.
• Core source run 38802248241 passes both normal and ASan/UBSan: all six native targets and 98 unique Python cases per mode, including the complete upstream tensor test.
• Hosted Code source checks remain required.

No change to model/toolset, resource bounds, permissions, handshake or cleanup. This is not a fix or success claim for the separate failed actual trial 38797816570; its rejected edit is being investigated independently. No new actual trial is dispatched by this change.
