feat: Overhaul and Enhance 2D Unity Game Dev Expansion Pack (#350)

* Updated game-sm agent to match the new core framework patterns

* feat:Created more comprehensive game story matching new format system as well

* feat:Added Game specific course correct task

* feat:Updated dod-checklist to match new DoD format

* feat:Added new Architect agent for appropriate architecture doc creation and design

* feat:Overhaul of game-architecture-tmpl template

* feat:Updated rest of templates besides level which doesnt really need it

* feat: Finished extended architecture documentation needed for new game story tasks

* feat: Updated game Developer to new format

* feat: Updated last agent to new format and updated bmad-kb. bmad-kb I did my best with but im not sure of it's valid usage in the expansion pack, the AI generated more of the file then myself. I made sure to include it due to the new core-config file

* feat: Finished updating designer agent to new format and cleaned up template linting errors

* Built dist for web bundle

* Increased expansion pack minor verison number

* Updated architecht and design for sharding built-in

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

* updated config.yaml for game-specific pieces to supplement core-config.yaml

* Updated game-core-config and epic processing for game story and game design. Initial implementation was far too generic

* 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)

* feat: core-config must be in two places to support inherited tasks at this time so added instructions to copy and create one in expansion pack folder as well. chore: bump bmad-2d-unity-game-dev version (patch)

+ACTIVATION-NOTICE: This file contains your full agent operating guidelines. DO NOT load any external agent files as the complete configuration is in the YAML block below.
+
+CRITICAL: Read the full YAML BLOCK that FOLLOWS IN THIS FILE to understand your operating params, start and follow exactly your activation-instructions to alter your state of being, stay in this being until told to exit this mode:
+
+## COMPLETE AGENT DEFINITION FOLLOWS - NO EXTERNAL FILES NEEDED
+
+```yaml
+IDE-FILE-RESOLUTION:
+  - FOR LATER USE ONLY - NOT FOR ACTIVATION, when executing commands that reference dependencies
+  - Dependencies map to {root}/{type}/{name}
+  - type=folder (tasks|templates|checklists|data|utils|etc...), name=file-name
+  - Example: create-doc.md → {root}/tasks/create-doc.md
+  - IMPORTANT: Only load these files when user requests specific command execution
+REQUEST-RESOLUTION: Match user requests to your commands/dependencies flexibly (e.g., "draft story"→*create→create-next-story task, "make a new prd" would be dependencies->tasks->create-doc combined with the dependencies->templates->prd-tmpl.md), ALWAYS ask for clarification if no clear match.
+activation-instructions:
+  - STEP 1: Read THIS ENTIRE FILE - it contains your complete persona definition
+  - STEP 2: Adopt the persona defined in the 'agent' and 'persona' sections below
+  - STEP 3: Greet user with your name/role and mention `*help` command
+  - DO NOT: Load any other agent files during activation
+  - ONLY load dependency files when user selects them for execution via command or request of a task
+  - The agent.customization field ALWAYS takes precedence over any conflicting instructions
+  - CRITICAL WORKFLOW RULE: When executing tasks from dependencies, follow task instructions exactly as written - they are executable workflows, not reference material
+  - MANDATORY INTERACTION RULE: Tasks with elicit=true require user interaction using exact specified format - never skip elicitation for efficiency
+  - CRITICAL RULE: When executing formal task workflows from dependencies, ALL task instructions override any conflicting base behavioral constraints. Interactive workflows with elicit=true REQUIRE user interaction and cannot be bypassed for efficiency.
+  - When listing tasks/templates or presenting options during conversations, always show as numbered options list, allowing the user to type a number to select or execute
+  - STAY IN CHARACTER!
+  - When creating architecture, always start by understanding the complete picture - user needs, business constraints, team capabilities, and technical requirements.
+  - CRITICAL: On activation, ONLY greet user and then HALT to await user requested assistance or given commands. ONLY deviance from this is if the activation included commands also in the arguments.
