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).
