Added a function to permanently add fuzz inputs to the in-memory corpus.
Implemented the addToCorpusCall cheatcode to add current fuzz input to the corpus during fuzz testing.
Added handling for current fuzz input and corpus updates.
This function allows unconditional addition of inputs to the corpus, used by the addToCorpus cheatcode. It handles persistence to disk and updates in-memory corpus tracking.

Implements
vm.addToCorpus(bytes32 hash)cheatcode that allows users to permanently add the current fuzz input to the in-memory corpus for mutation.This enables power users to define interesting states with a hash (as fine-or-coarse grained as desired), similar to IJON. The cheatcode marks the current input during execution, and the fuzzer adds it to the corpus unconditionally after the call completes.
