feat: execute optional type-valued compile-time storage

Browse Source 
Preserve owned optional metadata snapshots, nested presence, captures, checked unwraps and erased specialization identity. Verify imported nominal ownership across repeated compilation. Bootstrap: 299 passed. Native: 1080 programs plus 5 allocator programs passed with a temporary 120-second command deadline; bounded inline expansion exceeds the harness default of 30 seconds.
