Function hasPostCreateProjectCmdEvent

cmd/ddev/cmd/composer-create-project.go:494–520

hasPostCreateProjectCmdEvent checks if any installed Composer plugin subscribes to the post-create-project-cmd event. It parses the verbose output of `composer run-script --list` to extract plugin class names, then uses PHP reflection to check each plugin's getSubscribedEvents() method for the event

(app *ddevapp.DdevApp)

// reflection to check each plugin's getSubscribedEvents() method for the event.
// Returns true if any plugin handles post-create-project-cmd, false otherwise.
func hasPostCreateProjectCmdEvent(app *ddevapp.DdevApp) bool {

	_, _, err := app.Exec(&ddevapp.ExecOpts{
