## Wandering Objects

Fishing spots that move between rooms (**the filename is the ID** — `fishing_spot.yaml` → `fishing_spot`, no `id:` field):
```yaml
# data/objects/fishing_spot.yaml
name: fishing spot
gather:
    skill: fishing
    level: 1
    xp: 10
    base_wait: 4
    tools:
        - fishing_rod
    bait: fishing_bait
    success:
        base: 0.30
        per_level: 0.01
        cap: 0.90
    gather_message: "You cast your line into the water..."
    drops:
        - item_id: raw_trout
          weight: 100
          message: "You catch a raw trout!"
```

```yaml
# In a room:
objects:
  - id: fishing_spot
    wander_rooms: [7, 8, 9]
    wander_interval: 12
```

Objects teleport between rooms in their `wander_rooms` list. Players gathering from a
wandering object are silently interrupted when it moves.
