When enabled, in-game gift Pokemon (starters, trades, fossils) do not
count against a location's encounter limit. Both a gift encounter and
a regular encounter can coexist on the same route, in any order.
Persists encounter origin on the Encounter model so the backend can
exclude gift encounters from route-lock checks bidirectionally, and the
frontend can split them into a separate display layer that doesn't lock
the route for regular encounters.

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.
