refactor: fix parseCategory OCP violation with range-based iteration

Replace the switch/case in parseCategory() with range-based iteration
over all Category constants (Universal through _sentinel). This achieves
true OCP compliance: adding a new Category constant before _sentinel
automatically makes it available in parseCategory without modifying the
function.

Added _sentinel constant as the upper bound for range-based iteration,
with a comment explaining how to add new categories correctly.
