Update init --codespaces to handle existing devcontainer files
- Modified ensureDevcontainerConfig to check for existing devcontainer at default location - If .devcontainer/devcontainer.json exists, update it by merging gh-aw config - If no devcontainer exists, create at default location instead of subfolder - Update preserves existing name, image, extensions, features, and postCreateCommand - Added helper functions for merging extensions and features - Updated help text and success messages to reflect new behavior - Updated all tests to validate new behavior including merge scenarios - Manually tested both scenarios: new file creation and existing file update Co-authored-by: pelikhan <4175913+pelikhan@users.noreply.github.com>
