Malte UblandClaude Opus 5.5 484fc2cb13 Fold members stored after their namespace was created; skip the receiver read in JavaScript functions that never use this ...

- static-objects: a primitive member stored once by an unconditional
  top-level statement of the object's own file (app.math.EPSILON = 1e-9)
  reads as its literal where the read provably runs after the store: inside
  functions when the statements before the store run no code, and in later
  top-level statements of that file. SCRIPTC_SHAPE_FOLD_STORES=0 opts out.
- JavaScript functions read the ambient receiver at entry only when this
  occurs in their parameters or body outside nested non-arrow functions.
- npm case static-stores pins both, with the overlay on and off.

nsbench (n=20000, overlay on): 64.4 -> 36 ms.
