Mythic Dungeons 1.4.1

perf: probe spawn-block solidity at spawn time, not instance start

perf: lazily build reward GUI windows on first open instead of instance start

fix: 24 user-facing bugs across Mythic integration, parties, triggers, and procedural generation

Mythic:
- elapsed/timeleft placeholders and dungeonelapsedtime divided seconds by 20
- setdungeonvariable NPE'd on explicit type=
- dsignal, dungeon.var and isinDungeon resolved via first player in world (NPE outside dungeons, wrong instance in OneWorld), now use DungeonContext

Triggers:
- Player Leave fired for every instance's leave event
- Key Item with Use Anywhere fired and consumed items across OneWorld instances
- Block Detector gave no feedback for ANY

Party:
- /party invite rejected names prefixing the sender's
- invite expiry killed newer invites
- joining never left the old party
- recruitment password join fired a sync event off-thread and always crashed
- recruit "cancel" locked /recruit permanently
- PAF leader could be null in player lists
- revive message spammed the reviver instead of notifying everyone

Procedural:
- findRoom tested only one rotation per room
- room/connector blacklists ignored (identity equals)
- rotation-0 connector doors collapsed to one block
- straight-path connectors lost whitelists
- Minecrafty depth filter off by one
- requiredRooms leaked across layout retries
- block. generator left void seams at chunk borders
- pushable blocks pushed riders in the wrong direction

fix: async chunk load and null-spawn NPE in procedural spawn search

fix: strip Paper 26.1 world UUID metadata from copied instance worlds
