When the current deal's (seed, draw_mode, mode) triple matches an
entry in the rolling ReplayHistory, the HUD's tier-2 context row
now shows "✓ Won before" in the success-green colour. Cleared when
the active game itself is won (the on-screen victory cue is enough)
and on fresh deals the player hasn't beaten before.
The indicator answers a question the rolling-history feature
implicitly raised: when a new game starts on a seed the player has
already conquered, surface that fact so they know they can try for
a faster / higher-scoring win on the same layout. Seed re-rolls in
"Winnable deals only" + system-time seeds make this a natural pace
for the indicator to fire — usually empty, occasionally lit.
Implementation: new `HudWonPreviously` marker spawned in tier-2
alongside Mode / Challenge / DrawCycle. Driven by a separate
`update_won_previously` system rather than threading the marker
through `update_hud`'s ten-way query disambiguation. Reads the
existing `ReplayHistoryResource` from `stats_plugin`; gracefully
no-ops in headless tests that don't load StatsPlugin.
