fix Turing/Einstein engram root ID collision — reinstall with unique IDs

Both imprints shared root 8608f497 due to a concurrent install bug. Removed
the colliding entries, reinstalled via direct Engram API calls with auth key,
and updated registry with fresh distinct roots:
- Alan Turing:    cce1d430-be4e-420d-9d81-d32380ae7281
- Albert Einstein: 291f8502-8f60-4f57-a800-4e3e1425c9bd
