Boundaries are rectangular regions within zones that can trigger effects
when players enter or exit. Added BoundaryRegion dataclass with contains()
method, TOML parsing in load_zone(), and export support. Tests verify
parsing, export, and round-trip behavior.
Zones can now define spawn rules in TOML:
- [[spawns]] sections specify mob type, max count, and respawn timer
- SpawnRule dataclass stores configuration
- load_zone() parses spawn rules from TOML
- Added example spawn rules to treehouse zone (squirrel, crow)
This is configuration infrastructure only - actual spawning logic
will be handled by the game loop in a future phase.
Zone TOML files can now define portals using [[portals]] sections.
Each portal specifies coordinates (x, y), a target (zone_name:x,y),
and a label. Optional aliases are supported. Portals are
automatically created and placed in the zone when it loads.
Implements load_zone() and load_zones() functions to parse zone
definitions from TOML files. Wires zone loading into server startup
to register all zones from content/zones/ directory. Updates player
zone lookup to use the registry instead of hardcoded overworld check.
Includes tavern.toml as first hand-built interior zone (8x6 bounded).
Implements a module-level zone registry for looking up zones by name.
Includes register_zone() and get_zone() functions with comprehensive
tests covering single/multiple zones, unknown lookups, and overwrites.
