Implement VS Code Tool Integration

Phase 1: Core VS Code Tool Provider
- Created VSCodeToolProvider with 12 core tools (file ops, editor ops, commands)
- Implemented VSCodePermissions with 6 permission levels and security controls
- Integrated VS Code tools into UnifiedMCPServer tool discovery and routing
- Added comprehensive documentation in VSCODE_TOOL_INTEGRATION.md

Tools implemented:
- File Operations: read_file, write_file, create_file, delete_file, list_directory
- Editor Operations: get/set editor content, get/set selection, get active editor
- Commands: run_command (with whitelist), show_message
- Workspace: get_workspace_folders

Security features:
- Permission levels: read_only, editor, filesystem, terminal, git, admin
- Path sandboxing to prevent access outside workspace
- Command whitelisting for safe operations
- Audit logging for all VS Code tool operations

Next: Implement actual VS Code Extension API bridge and language services
