fix: resolve blacklist false-positives for specific function names

[Anve94]

Changed

• Git blacklist now matches on words instead of characters by default.
• The git blacklist configuration for rejecting accidentally commited merge conflicts now properly reflects the
  full set of characters used by git.

Fixed

• Resolved issue where the updated git blacklist configuration would provide a false positive result
  on functions ending with add() or odd() due to checks on dump and die dd() statements.

Added

• Git blacklist now checks for exit() usage.
