Session 46: Grade card intel + name normalization + pitchers (2122 tests)

Three focused P1 fixes on the Session-45 snapshot model.

- Grade card intel ROOT CAUSE: gameLogService is NBA/WNBA-only (offline Python),
  so MLB props never got l5_avg/l20_avg and buildIntelFields returned {}. Wired
  MLB game logs into featureCache.gameLogFeatures via mlbStatsAdapter.getPlayerStats
  (pure mlbGameLogFeatures + MLB stat_type->field map). buildIntelFields gained
  playerStats/projection fallbacks for partial intel.
- Player name normalization: src/utils/playerName.js (+ web/src/lib copy):
  normalizeName -> {display,key}. Strips periods, de-dots suffix, accent-folds
  the key. Applied in snapshotService grouping, slateAdapter grade index +
  player-strip merge (variants collapse, longest name shown), and
  playerIntelService. "A.J. Ewing"/"AJ Ewing" + "Jazz Chisholm"/"Jr." now merge.
- MLB starting pitchers: new GET /api/schedule/:sport/pitchers (probablePitchers
  service wrapping mlbStatsAdapter.getScheduleWithPitchers + best-effort ERA).
  Slate fetches it, builds a team->pitcher map (full name + mascot match),
  attaches pitchers to MLB GameCardData. + Next proxy.

Backend 2100 -> 2122 tests (+22), 176 suites. Web build clean (exit 0).

+## Grade Intel + Name Norm + Pitchers (Session 46 — non-obvious)
+- **Grade-card intel root cause:** `buildIntelFields` reads l5_avg/l20_avg/
+  opp_rank_stat/rest_days from the feature vector. `gameLogService.getGameLogs`
+  is NBA/WNBA-ONLY (offline Python service) → MLB props had NO recent/season
+  averages → intel always empty. FIX: `featureCache.gameLogFeatures` has an MLB
+  branch using `mlbStatsAdapter.getPlayerStats` + the pure `mlbGameLogFeatures`
+  (MLB stat_type→game-log field via `MLB_LOG_FIELD`). If you add an MLB stat
+  type, add it to `MLB_LOG_FIELD` or its intel won't compute. `buildIntelFields`
+  also takes `{ playerStats, projection }` fallbacks — don't remove the resilience.
+- **Player name normalization:** `src/utils/playerName.js` is the source of truth
+  (frontend copy at `web/src/lib/playerName.js` — keep them identical; a test
+  cross-checks). `normalizeName(raw)→{display,key}`: display strips periods +
+  de-dots suffix (keeps accents); key accent-folds + suffix-strips for comparison.
+  Used in snapshotService grouping, slateAdapter grade-index + player-strip
+  merge, and playerIntelService. `sanitizePlayerName` now returns the de-dotted
+  display ("A.J. Ewing"→"AJ Ewing") — tests that asserted the dotted form were
+  updated.
+- **MLB pitchers:** the ESPN `/api/schedule` has NO probable pitchers. They come
+  from `GET /api/schedule/:sport/pitchers` (MLB) → `probablePitchers` service →
+  `mlbStatsAdapter.getScheduleWithPitchers`. The Slate matches them to games by
+  team (full name OR mascot via `slateAdapter.buildPitcherMap`/`pitchersForGameTeams`).
+  ERA is best-effort (season stats per pitcher id, cached).
