Session 44: Make it visible — VYNDR archetype names, grade intel, schedule fix, landing page (2061 tests)

Frontend + wiring only. Wires existing backend into the pages users see.

- VYNDR Original archetype rename (41) across archetypeService.js + lib/
  archetypes.js + ArchetypeBadge, each keeping legacyName (resolves stale data).
  Judge -> BOMBER. Old POWER PULL slot -> WHIFF strikeout-artist pitcher.
- BACKEND_HANDOFF.md: canonical frontend<->backend data contract.
- Grade card intel: scan/page.tsx now forwards the engine's intel fields
  (season_avg/form/usage/matchup_grade/archetype/...) into mapScanToGradeResult
  -> STAT CONTEXT + VYNDR INTELLIGENCE sections populate. The chain already
  preserved them (tierGating + /api/scan spread); the page was dropping them.
- Schedule freshness: slateAdapter.isRelevantGame drops completed games >24h
  old; Slate.filteredGames applies it. (TTL already 60s.)
- Landing: Features.tsx rewritten to user-facing copy (no Point-biserial/Zone
  14/ABS/Phi-coefficient).
- Depth chart Next proxies added (/api/stats/lineup|depth|cascade) - were 404.
- GameCard swap DEFERRED (Kev): legacy on-demand card stays as a bridge until
  the snapshot pipeline populates the grades cache; vyndr/GameCard swaps in then.

Backend 2045 -> 2061 tests (+16), 167 suites. Web build clean (exit 0).
