Whistle & Wander

## Whistle & Wander v1.1.1 — Hotfix & Spawn Balancing Update

### 🐾 Spawn Overhaul & Bug Fixes:
* **Fixed Pebble Pup Spawns:**
  * Fixed an issue where Pebble Pups mistakenly spawned on beaches and low-altitude terrain in direct sunlight.
  * Pebble Pups now **strictly** spawn deep underground (Y ≤ 55 with solid cave ceilings) or on high rocky mountain peaks (Y ≥ 80).
  * Removed Sand from allowed floor blocks and completely blacklisted beaches, oceans, and rivers.
  * Rebalanced spawn weights (from 45–50 down to a cozy 10–16) and restored strict solo spawns.
  * Untamed Pebble Pups now properly despawn when far away from players, keeping the ambient mob cap clean.
* **Fixed Sandy Dustbunny in Deserts:**
  * Fixed invalid `#minecraft:is_desert` tag that prevented Sandy Dustbunnies from spawning in vanilla deserts. Added support for `#forge:is_desert` and explicit `minecraft:desert`.
  * Relaxed floor constraints so Dustbunnies can hop around sand, sandstone, red sandstone, and gravel.
* **Fixed Snow Puff in Snowy Biomes:**
* **Fixed Mossy Hopper in Lush Caves:**
  * Implemented custom spawn rules for Mossy Hoppers allowing them to spawn inside dark Lush Caves on Moss Blocks, Clay, Rooted Dirt, and Azalea.
  * Added spawn support for Taiga biomes (`#minecraft:is_taiga`).
* **Overall Balancing:**
  * Rebalanced spawn chances and category weights across all 6 companions for an authentic Vanilla+ experience.
