tiennm99 d0c75e84b1 test: add characterization tests for lib layer ...

Cover classic-mode comparison rules, game-engine state machine and
localStorage persistence, and champion-data search/seeding/loading with
Vitest. Storage keys are asserted literally so returning players' saved
games and stats cannot silently break.

Node environment with a hand-rolled localStorage stub; fixtures are four
hand-written champions so the weekly data sync cannot destabilise the
suite.
