feat(tavern): proper tavern — real bar, kegs, bottles, tables+chairs, windows, rug

Used the sheet's hand-labelled roguelikeSheet_meta.json to pick the RIGHT tiles
instead of guessing:
- New tile kinds + coords (window, counter, keg/barrel, shelf, table, chair,
  crate, rug, door) in sceneModel TAVERN_LEGEND/TILE_OF + assetPacks tileMap.
- tavernMap redesigned: windowed walls, a bar counter with a shelf of bottles
  behind it and a keg (beer!) at each end, six tables each with a chair, a
  central rug, corner barrels/crates, and a door. Chairs are walkable so standing
  on one reads as sitting. Warm wood floor color (was a dark green in the fallback).
- Bartender now stands BEHIND the bar (spawn + roam confined to the row between
  the top wall and the counter, sealed off by it).

Still TODO from feedback: a cat (no cat sprite on the sheet — needs an asset) and
richer bar bottles. Suite 57 suites / 413 tests green.
