Track aiOpponent in game store; show a pill badge in the topbar for AI
games, update turn label to "<Brain> is moving…" on the bot's turn,
and suppress the disconnected-opponent banner when the opponent is a bot.

Svelte 5 $effect tracks every $state read inside its body. The
lifecycle effect that calls game.connect(gameId) implicitly read
state.ws (inside connect()) and then wrote to it, producing an
effect_update_depth_exceeded loop. Symptom in production: the
browser opened ~12 WS connections/sec, none completed the upgrade
handshake, and the lobby flow appeared stuck on 'waiting for
opponent' (the opponent's WS never stabilized long enough for the
server to send 'joined'). untrack() opts the call out of dep tracking.

Svelte 5 runes ($state, $derived, $effect) only run through the
compiler in .svelte and .svelte.ts/js files. A plain .ts file leaves
$state(...) as a literal call at runtime, causing
"ReferenceError: $state is not defined" and a blank page.
