When any variant rule is enabled, the encounter modal switches from
the game's regional dex to an all-Pokemon search (same debounced
API pattern as EggEncounterModal). A new "Run Variant" section in
rules configuration groups these rules, and badges render in amber.

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.
