fix(vercel): fix silent project-rename leak in update_project

- update_project had no dedicated rename field and just returned base directly, so a stale value from create_deployment's unrelated 'name' subBlock (Project Name for the deployment) could silently flow through and rename a project on update
- add a dedicated 'New Project Name' field for update_project, wired with a direct override so it always takes precedence over any stale leaked value
