fix: use keyboard shortcuts instead of context menu clicks

Playwright's click() does not reliably trigger actions on VS Code
Electron context menu items (the menu stays open). Switch to:
1. Right-click to select tree item and set focusedView
2. Escape to close context menu (returns focus to tree)
3. F2/Delete keyboard shortcut to trigger rename/delete commands
