- Update _find_container to use targeting module (prefix + ordinal)
- Update cmd_put to use find_in_inventory directly
- Add 'get all from <container>' support with portable item filtering
- Add comprehensive tests for all container grammar features
Replace local exact-match helpers with targeting module calls for
prefix matching and ordinal disambiguation. Works in get, drop, and
container extraction (get X from Y).
Containers now display their state when viewed:
- Closed containers show "(closed)"
- Open empty containers show "(open, empty)"
- Open containers with items show "(open, containing: item1, item2)"
This applies to both ground items in the look command and inventory items.
Added _format_thing_name helper to both look.py and things.py to handle
the display formatting consistently.
Inventory saved as JSON list of thing template names in an inventory
column. Migration adds column to existing databases. load_player_data
returns inventory list, save_player serializes Thing names from contents.
Object.move_to() handles containment transfer: removes from old location's
contents, updates location pointer and coordinates, adds to new location.
get/drop commands use move_to to transfer Things between zone and inventory.
Supports name and alias matching for item lookup.
