fix: use strict equality for boolean comparison in store.ts

Replace loose equality (==) with strict equality (===) for isListening
boolean comparison on line 253. This follows JavaScript best practices
and prevents potential type coercion issues.

The change is in the onTrigger callback within createSetupStore function,
which handles debugger events during development mode.
