Description

This PR implements a complete VS Code extension that provides a visual Kanban board interface for Task Master projects. Building on the scaffolding from PR #989, this delivers a production-ready extension with React-based UI, MCP integration for real-time synchronization, and professional CI/CD workflows for marketplace publishing.

BREAKING CHANGE: Extension requires publisher setup and marketplace keys

Publisher and extension naming decisions required:

• Update publisher field from placeholder 'DavidMaliglowka'
• Choose unique extension name (currently 'taskr-kanban')
• Select appropriate extension icon
• Configure CI secrets (VSCE_PAT, OVSX_PAT) for publishing

See apps/extension/docs/ for detailed setup instructions
