fix(javascript): converge cyclic aliases with explicit projection widening

Browse Source 
Replace initializer-history and full-path enumeration with a finite projection
join at each source read. Retain conservative local returned-reference effects
and disclose precision loss through static, semantic and captured-web results.
Close full-binding callback cycles while preserving narrowed read semantics.
