fix: resolve editor launch issue on macOS for subagent editing

- Fixed ENOENT error when launching external editors (VS Code, etc.)
- Added proper editor command mapping (vscode -> code, neovim -> nvim, etc.)
- Implemented command existence check to find available editor executable
- Supports both macOS and Windows platform-specific commands

Fixes #1180
