Open Route 29 and Cherrygrove City

- Enable Route 29, its Route 46 gate, Cherrygrove City and its buildings.
- Run item balls through FindItemInBallScript and fruit trees through
  FruitTreeScript, with a native daily reset of the daily engine flags.
- Port the Pokémon Center nurse (HealParty with the PP Up clamp,
  CheckPokerus, phone-call checks) and record the whiteout spawn on
  entering a Pokémon Center, as EnterMapWarp does.
- Port standard Poké Marts with keyboard, D-pad and pointer menus.
- Add the recoil battle command (Struggle) and VAR_BOXSPACE.
- Save fruit trees, the daily reset day and the last spawn map; older
  version-3 backups migrate by absence.

 Scripts run on a private draft. The world presents each yielded effect, then resumes the script with the player's answer or when the animation ends. The draft is committed only when the script ends. A save made during a scene returns the committed state, and coordinate events rewind to the source of the triggering walk or two-tile jump. Saves during movement also retain the source tile until arrival events run, including across map connections. A failed scene restores the positions it had changed. As in `LoadMapObjects`, map objects spawn when the map loads. Later flag changes do not remove objects already shown; only `appear` and `disappear` do.
 
-The opening scenes currently run end to end from the ROM: Mom's Pokégear, weekday and DST scene, the teacher at the west edge, the rival at the lab window, Elm's introduction with its yes/no loop, the lab's exit guard, the starter choice with `pokepic`, `givepoke` and the nickname prompt, Elm's directions and the aide's Potion through the ROM's own `GiveItemScript`. `callasm` accepts only explicitly empty routines or native translations; battle whiteout hooks are present but await full flow validation.

+Route 29 and Cherrygrove are enabled with item balls, fruit trees and the daily reset, the Pokémon Center nurse and the recorded whiteout spawn. Next: NPC roaming, trainer sight lines and trainer battles, capture with the catching tutorial, and party, bag and Pokégear menus over the native models. Other specials stay refused until translated.
