fix(javascript): preserve values captured before later assignments (#4196)

Select binding facts at reads without mixing whole-binding and temporal values. Share conditional activation rules, preserve partial expression order, and bound immutable ancestry work. Memoize temporal results within each query using initializer identity, capture point, budget and dependency proofs; preserve depth limits and source Evidence.

Fixes #3881
