The live staleness bug: liveTick refetched ESPN summaries every 20s but
the cache TTL was 5 minutes, so in-play stats/timeline barely moved.
Summaries now take a live flag (15s TTL in play), the scoreboard TTL
drops 20s->5s, and polling gets three tiers (8s in-play / 20s near
kickoff / 10m idle) via a pure, tested cadence module. The
football-data fallback is throttled to one attempt per 15s so the 8s
cadence can never breach its 10 req/min cap. Enrichment runs every 5m
(was 20m); client refetch intervals tighten to 10s (live match page)
and 30s (scoreboard).

- src/lib/model/inplay.ts: in-play win probability — remaining goals modelled as
time-scaled Poisson processes convolved with the current score; recomputed each
tick. 4 vitest cases (locks at FT, lead grows decisive over time, sums to 1).
- ESPN summary normalizer extended with the live event timeline (keyEvents);
preview now carries liveStats + events. Scheduler refreshes LIVE matches'
summaries every live tick (~20s) for fresh stats/timeline.
- /match/:num is now a live match center: when live it shows in-play win
probability (driven by the WS score/clock), match stats bars and an event
timeline, polling while live; preview content for scheduled games, recap when
finished. Verified with a simulated live state (94% live vs 81% pre-match).
