The votable() method had incorrect logic that allowed voting on recently
voted blocks when it should have prevented them. Fix inverts the logic to:

  • Prevent repeated votes on the same root/hash pairs within spacing window
  • Allow immediate voting on different blocks with same root (competing forks)

Additional changes:

  • Remove vote spacing check from vote_generator reply()
  • Update vote_spacing to track latest fork votes per root
  • Fix tests to reflect correct spacing behavior

fix(vote_generator): Properly spaces votes for same block while allow…

…ing immediate votes

for competing forks.

Key changes:
- Remove vote spacing check from reply() in vote_generator.cpp
- Update vote_spacing implementation to track most recent fork votes
- Fix tests to reflect new vote spacing behavior

I modified the vote spacing class to track votes by qualified root, which simplified the code and it eliminated the need to handle ambiguity.
