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
semanticObjectPropertyReferences scanned every property of an object
literal on each call, and member-mutation tracking calls it once per
write, so N writes to an N-property literal cost O(N^2).
For an exact string or number key, a property with another static name
only updates override bookkeeping for that other name, which the key
never reads. Index each literal once by static name, keeping spreads,
computed keys and __proto__ data entries for every key, and walk only
the relevant members in reverse source order. Wildcard and selection
keys keep the full scan.

Resolve this, private fields and super reads through receiver-aware references. Separate instance fields from prototype descriptors, preserve alternative inheritance branches and allow finite repeated getter paths.
Add domain precision regressions and compiled CLI/MCP coverage for the four reported getter shapes.
