feat: Implement comprehensive workspace linking solution for vim plugin

This commit establishes a complete workspace setup enabling local development
of the vim plugin while preserving Arabic cursor fixes and ensuring proper
dependency resolution.

**Key Changes:**
• Configure workspace package for @replit/codemirror-vim
• Add git submodule pointing to fix/cursor-arabic-connected-characters branch
• Implement TypeScript paths configuration for CodeMirror type resolution
• Add automatic vim plugin pre-build with yarn start
• Create comprehensive documentation and troubleshooting guides

**Workspace Benefits:**
• Real-time vim plugin development without git commits
• Preserved Arabic cursor positioning fixes
• Proper peer dependency resolution eliminating CodeMirror conflicts
• Standard TypeScript module resolution patterns
• Cross-platform compatibility

**Technical Solution:**
The workspace uses peer dependencies with TypeScript paths configuration
to force all @codemirror/* imports to resolve from the root node_modules,
eliminating duplicate type declarations that caused build failures.

**Documentation Added:**
• context/WORKSPACE_LINKING_SOLUTION.md - Complete solution guide
• Updated CLAUDE.md with workspace tooling and troubleshooting

Fixes workspace setup with stable Arabic cursor fixes ready for
development of enhanced vim stability features.
