Review follow-up for the Hidden Core broadcast fix. The strip's queue rules are
now pure, exported helpers (tickerSupersedes, enqueueTickerLines,
pruneTickerLines, nextTickerLine) with unit tests across a round 14 -> 15
change, instead of source regex checks only.
A player's newer BOSS_HIT line of the same round replaces their older one,
queued or on screen (it names a higher threshold), so a burst finish shows its
highest milestone before the round ends and the last round's lines are dropped.
Lines now carry playerId from main.js. The solo match test is labelled 绝境
(HARD), the difficulty it runs.
