Trey t b5daddefd3 Add UI redesign: design system, dashboard density, game intelligence, feed tab, league leaders
Phase 1 - Design System: DesignSystem.swift (typography, colors, spacing
constants) and DataPanel.swift (reusable panel container with 3 densities
and optional team accent bar).

Phase 2 - Dashboard Density: LiveSituationBar (compact strip of all live
games with scores/innings/outs), MiniLinescoreView (R-H-E footer for game
cards), DiamondView (visual baseball diamond with runners and count).
Dashboard shows live situation bar when games are active. Game cards now
display mini linescore for live/final games.

Phase 3 - Game Center Intelligence: WinProbabilityChartView (full-game
line chart using Swift Charts with area fills), PitchArsenalView (pitch
type distribution with velocity bars). GameCenterViewModel now stores
full WP history array instead of just latest values.

Phase 4 - Feed Tab: MLBWebDataService (fetches league leaders from Stats
API, news headlines, transactions), FeedViewModel, FeedView with
reverse-chronological feed items. FeedItemView with colored edge bars
by category. Added 5th "Feed" tab to both tvOS and iOS.

Phase 5 - Intel Tab: LeaderboardView (top-5 stat cards with headshots),
integrated into LeagueCenterView. Renamed tabs: Games->Today,
League->Intel. LeagueCenterViewModel now fetches league leaders.
