Remove unused nuzlocke rules, reorganize into core and playstyle

Remove firstEncounterOnly, permadeath, nicknameRequired, and
postGameCompletion from the rules system — they are either implicit
(it's a nuzlocke tracker) or not enforced. Move levelCaps to core
(it's displayed in the sticky bar). Create a new "playstyle" category
for hardcoreMode and setModeOnly — informational rules useful for
stats but not enforced by the tracker. Remove the completion category
entirely. Add sub-task beans for the rules overhaul epic.
