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).

+## Name Norm + Intel + Ticker (Session 47 — non-obvious)
+- **Name normalization is now complete:** `playerName.js` (both copies, kept
+  identical) strips parenthetical team tags ("(STL)"), de-dots, suffix-strips,
+  accent-folds the key, AND resolves first-name nicknames via the `NICKNAMES`
+  table ("matt"→"matthew"). `nameKey` does the nickname resolution; `normalizeName`
+  does display/key. To add a nickname, edit BOTH copies. The SLATE displays the
+  normalized de-dotted name (`buildPlayerStripsFromProps` → `normalizeName().display`),
+  not raw PropLine — that's why "AJ Ewing" shows, not "A.J. Ewing".
+- **MLB VYNDR INTELLIGENCE fields** come from `mlbGameLogFeatures`: `rest_days`
+  (gap-1 between the two latest game dates; 0 = B2B), `ab_per_game` (usage). If a
+  field is missing from the card, check that `mlbGameLogFeatures` produced it and
+  `buildIntelFields` has a branch (usage reads usage_rate→minutes→ab_per_game;
+  matchup reads opp_rank_stat→bvp_advantage).
+- **Ticker SCAN dedup:** `pushTickerItems` keeps one SCAN per sport (via the
+  `sport` field on the event, or parsed from the text prefix for legacy items).
+  MOVE/GRADE are time-specific and never deduped.
+- **BOMBER threshold is prorated for mid-season** (`hr>=15` strong / `hr>=10`
+  moderate). If you re-tune archetype thresholds, remember season totals are
+  partial mid-season — don't use full-season cutoffs.
