Add LLWS bracket Monte Carlo simulator (#280)
* Add LLWS bracket Monte Carlo simulator

Simulates the 20-team Little League World Series: pool play round-robin
(5 teams/pool, top 2 advance) → 4-team double-elimination per side
(US and International) → consolation game → World Series final.

Uses championship futures odds as the sole win-probability signal.
Pool assignments are auto-detected from externalId: bare "US"/"Intl"
randomizes pools each simulation (pre-draw mode); "US:A"/"Intl:B" etc.
uses fixed assignments (post-draw mode). Sides can differ.

* Fix oxlint violations in LLWS simulator

- Replace non-null assertions with null-safe access (! → ?? / optional chaining)
- Replace .sort() with .toSorted() per linting rules
- Promote bump() to simulate() scope and pass it into simulateSideBracket,
  removing the need to pass counts into that function
