fuzz: wallet: add target for `TransactionCanBeBumped` #33916

1. 
   brunoerg commented at 2:07 PM on November 20, 2025: contributor

   This PR adds a fuzz target for the TransactionCanBeBumped function. This function checks if a transaction can be bumped based on:

   1. Transaction has descendants in the wallet.
   2. Transaction has descendants in the mempool.
   3. Transaction has been mined.
   4. Transaction was already bumped.
   5. Transaction has inputs that are not mine.

   This target will create scenarios to exercise all these cases. For the scenario (2), it has a mocked CTxMemPool that has a function to update the descendant state on mempool - this way we can speed up the target by avoiding to interacting with the mempool to really create descedants (e.g. creating blocks to trigger it).

   Also, the CheckTransaction calls are to avoid UB on SetSpentKeyState - e.g. by calling it with a transaction without any output.

   PR adds new fuzzing target. Target wallet_tx_can_be_bumped.

   Ran fuzzer for 2 hours without issues, Codecoverage equals to what is reported. New Target is NOT deterministic, but I'm also not sure what to change to make it deterministic (if it's even feasible)

   This fuzzer increases fuzzing coverage :

    Try to run the tests locally, according to the documentation. However, a CI failure may still happen due to a number of reasons, for example:

    • Possibly due to a silent merge conflict (the changes in this pull request being incompatible with the current code in the target branch). If so, make sure to rebase on the latest commit of the target branch.

    • A sanitizer issue, which can only be found by compiling with the sanitizer and running the affected test.

    • An intermittent issue.
