refactor: Move ink source files to scenarios/ink and add compilation script

Consolidated all ink source files into scenarios/ink directory for better
organization. All ink source files and documentation are now in the same
location as their compiled JSON output.

Changes:
1. Moved all .ink source files from story_design/ink/ to scenarios/ink/
   - chen_hub.ink and supporting files
   - netherton_hub.ink and supporting files
   - haxolottle_hub.ink and supporting files
   - All other ink source files

2. Moved documentation files to scenarios/ink/
   - INK_BEST_PRACTICES.md
   - NPC_HUB_ARCHITECTURE.md
   - ONGOING_CONVERSATIONS_README.md
   - README.md

3. Added scripts/compile-ink.sh
   - Automatically compiles all .ink files in scenarios/ink/
   - Outputs JSON to the same directory
   - Shows colored output with success/failure status
   - Provides compilation summary

Usage:
  ./scripts/compile-ink.sh

This consolidates the ink development workflow into a single directory
and provides an easy way to recompile all ink files after making changes.
