Session 47: Name normalization + grade intel + ticker polish (2149 tests)

- Name normalization completed: NICKNAMES table (Matt↔Matthew, Mike↔Michael...) resolved in nameKey, parenthetical team-tag strip "(STL)", verified accent-fold (Iván/Ivan, José/Jose). Slate strip now DISPLAYS the normalized de-dotted name ("AJ Ewing" not "A.J. Ewing") via buildPlayerStripsFromProps. - Complete MLB VYNDR INTELLIGENCE: mlbGameLogFeatures derives rest_days (days off between latest games; 0=B2B) + ab_per_game (usage). buildIntelFields renders usage as "X AB/G", rest as B2B/Xd, matchup from bvp_advantage fallback. - Ticker SCAN dedup: pushTickerItems keeps one SCAN per sport (sport field or text-prefix parse for legacy); MOVE/GRADE preserved; cap 50. - BOMBER threshold prorated for mid-season (hr>=15 strong / >=10 mod) so June sluggers classify BOMBER not FLEX/DRIVER. Backend 2122 -> 2149 tests (+27), 179 suites. Web build clean (exit 0). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
