Fixes #293

Sweep: PR Review

pkg/hintrunner/hinter/zero_dict.go

New methods SetFreeOffset were added to both ZeroDictionary and ZeroDictionaryManager to allow direct setting of the freeOffset field.

---

pkg/hintrunner/zero/hintcode.go

A new constant string dictSquashUpdatePtrCode was added to update the current_ptr of the DictTracker to the end address of the squashed dictionary.

Sweep Found These Issues

• The new code does not handle the case where __dict_manager.get_tracker(ids.squashed_dict_start) returns None, which could lead to a NoneType attribute error.

Line 120 in ce52a88

dictSquashUpdatePtrCode string = "# Update the DictTracker's current_ptr to point to the end of the squashed dict.\n__dict_manager.get_tracker(ids.squashed_dict_start).current_ptr = \\\n ids.squashed_dict_end.address_"

The changes add support for the dictSquashUpdatePtrCode hint type in the GetHintFromCode function by introducing a new case and its corresponding hinter creation function call.

pkg/hintrunner/zero/zerohint_dictionaries.go

Added functions to create and handle a new hint "DictSquashUpdatePtrCode" for updating the current_ptr of a DictTracker.

Sweep Found These Issues

• If __dict_manager is not in scope, the function returns an error without providing a mechanism to initialize or handle this case.

Lines 422 to 424 in ce52a88

	dictionaryManager, ok := ctx.ScopeManager.GetZeroDictionaryManager()
	if !ok {
	return fmt.Errorf("__dict_manager not in scope")
