amyanger 7436ac8e20 fix(javascript): drop built-in effects for visibly replaced globals (#4565)
The semantic collectors admitted Node timers, fetch, WebSocket, JSON.parse
and global coercions from the identifier spelling alone, so a source that
replaced those globals (`setTimeout = () => null`) still produced resolved
built-in effects. Require the existing isUnmodifiedGlobalReference guard,
which the static analyzer already uses for fetch and WebSocket, before
admitting these effects.

The guard treats any visible possible write as a replacement without
evaluating order or reachability, so computed global writes and guarded
polyfills also remove the resolved effect. The workflow docs now say so.

Fixes #3367

e4c3d72396 fix(javascript): converge cyclic aliases with explicit projection widening
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.
