Scribe v1.2.1 - .Get() & .Clone() Fixes

• Root whole-data reads (Get, Clone, Observe, Changed) now return exactly your declared roots: no internal _Scribe, and Scribe.Session roots are finally included.
• Get() is frozen, so a stray Get().Coins = 1 raises instead of writing silently.
• Scribe.ServerOnly fields left the client type, so reading one there is a build error, not a nil.
• Use Clone() to edit, Data.Export for internals.
