Port the Smart AI effect handlers (#28)

Translate every AI_Smart_EffectHandlers entry, so trainers with the Smart layer are no longer refused. The AI's type checks keep the CheckTypeMatchup bug: they read the move type and Foresight flag through hBattleTurn, and Conversion2's write to the player's move type persists.

The reference emulator runs the unmodified AI_Smart routine over 6,024 states per browser, comparing scores, Random consumption, hBattleTurn and the player's move type. Validated with 579 unit tests, 151 browser tests, native/reference builds and reference/vendor/release checks. Kurt's balls, Park and Safari balls and special battle types remain on #28.

+## Smart AI handlers: 2026-10-03
+
+Codex resumed card #28 after `32d736e` and stopped at its usage limit at
+13:21 UTC with an uncommitted Smart AI translation (`smart-ai.ts`), partial
+battle wiring and a failing emulator spec. Claude Code took it over.
+
+- The spec showed 35 of 6,024 states differing, in five handlers. Encore,
+  Roar/Whirlwind, Baton Pass and Perish Song came from `CheckTypeMatchup`
+  ignoring the type in `a`: it reads the move type and Foresight flag through
+  `hBattleTurn`. The AI now tracks the turn and both move structs' types;
+  `checkPlayerMoveTypeMatchups` takes the type and flag. Conversion2's write
+  to the player's move type persists in the battle.
+- Psych Up sums `NUM_LEVEL_STATS` (8) bytes. The eighth is only ever reset to
+  7 or copied, so the 7-entry sum is equivalent; the spec now writes it as 7.
+- The spec randomizes the starting turn and the player's move type and also
+  compares them afterwards. It passes 6,024 states per browser; a one-off
+  run with another seed passed 18,072 per browser.
+
+Validation: 579 unit tests passed (3 skipped); without the ROM 138 passed,
+444 skipped. Browser suite: 151 passed, 19 intentional skips. Both builds,
+reference/release/vendor checks and `git diff --check` passed. No CI or
+physical-device validation.
+
+Next on #28: Kurt's balls, Park and Safari balls, and special battle types.
+Other boundaries listed in the previous section are unchanged.
