feat: round-recap script + fix stuck-LIVE knockout poller gap

[dommango]

Two related changes that came out of prepping the post-quarterfinals update email.

1. scripts/round-recap.ts — generalized recap for the update email

Read-only ops helper for drafting the per-round Knockout Challenge update email. Generalizes scripts/r32-recap.ts to any knockout round and folds in the standings block from scripts/challenge-progress.ts, so one run prints all three sections:

DATABASE_URL=... npx tsx scripts/round-recap.ts [ROUND]   # R32|R16|QF|SF|FINAL, default QF

1. Round results — scorelines from Match/Result, ⚡ PENALTIES flag; skips non-FINAL.
2. Next-round matchups — now-set pairings via resolveBracket(officialResults).
3. Knockout Challenge progress — entrant count, top-10, perfect-R32 count, average score.

Additive; existing r32-recap.ts / challenge-progress.ts untouched. Reused for SF + Final.

2. lib/sports/poll.ts — fix knockout matches stranded LIVE past their window

shouldPollNow() only polled when a match's scheduledAt was within [now-155min, now+5min]. A knockout match whose full-time result lands after that window closes (extra time + shootout, long stoppages, or a lagging FT status) was stranded LIVE forever — the window closed before the finalizing poll ran, so FINAL was never fetched.

Observed live: QF match 100 froze at its in-play snapshot (2-1, LIVE) when its window closed ~2h35m after kickoff; every poll since returned skipped: "no match in live window", so scores + SF seeding stalled for ~13h.

Fix: add a backstop — keep polling any scored match (bronze 103 excluded; never finalized via the API) that has kicked off but isn't FINAL yet, for a generous grace period after kickoff. Self-terminating once it flips to FINAL.

Note: match 100 was finalized manually in prod (Argentina 2-1, authoritative MANUAL entry) to unblock the semifinals/recap immediately; this fix prevents recurrence for SF & Final.

Verification

• npm run typecheck clean for changed files; npx vitest run lib/sports lib/pool → 416 passed.
• Ran round-recap.ts QF against prod: all four QF final, SF = France v Spain / England v Argentina, standings recomputed (avg 22.9 → 25.9 after QF points applied).
