Session-scoped globals refactored into a resettable cell registry

Session state is now reset through a central registry, so switching sessions clears things more reliably.

What

Module-level mutable globals with hand-written getter and setter pairs were replaced by cells produced by a factory and tracked in a registry.

Details
  • the factory returns a {get, set, reset} cell and pushes it onto the registry
  • session reset now clears the maps and loops the registry calling reset() instead of nulling each variable by name
  • a number of one-line getters and setters were removed as a result
Evidence

reset: () => {

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
