Show install summary and cron/config viewer

Display an installation summary (including downloaded script SHA256, source, install path, config, log file, and cron schedule) and make script review optional before install. Add an interactive View menu to inspect the installed worker script, cron configuration, or both; implement view_worker_script, view_cron_config (shows cron entry, human-readable schedule, config contents and excluded patterns, and log file size), and cron_to_human helper. Also update prompt wording and the View option description.
