* chore: bump bmad-2d-unity-game-dev version (patch)

* feat: Fixed issue with multi-configs being needed. chore: bump bmad-2d-unity-game-dev version (patch)

* Chore: Built web-bundle

* feat: Added the ability to specify the unity editor install location.\nchore: bump bmad-2d-unity-game-dev version (patch)

# Validate Game Story Task
## Purpose
To comprehensively validate a Unity 2D game development story draft before implementation begins, ensuring it contains all necessary Unity-specific technical context, game development requirements, and implementation details. This specialized validation prevents hallucinations, ensures Unity development readiness, and validates game-specific acceptance criteria and testing approaches.
## SEQUENTIAL Task Execution (Do not proceed until current Task is complete)
### 0. Load Core Configuration and Inputs
- Load `{root}/core-config.yaml` from the project root
- If the file does not exist, HALT and inform the user: "core-config.yaml not found. This file is required for story validation."
- Extract key configurations: `devStoryLocation`, `gdd.*`, `gamearchitecture.*`, `workflow.*`
- Identify and load the following inputs:
- **Story file**: The drafted game story to validate (provided by user or discovered in `devStoryLocation`)
- **Parent epic**: The epic containing this story's requirements from GDD
- **Architecture documents**: Based on configuration (sharded or monolithic)
