refactor(cli): deduplicate command options between top-level and agent subcommands

Extract addXxxOptions() builder functions for all 9 shared commands
(ls, run, attach, logs, stop, delete, send, inspect, wait) so both
paseo <cmd> and paseo agent <cmd> use a single source of truth.

Fixes drift where agent subcommands were missing --wait-timeout (run),
--worktree/--base/--image (run), --since (logs), and --image (send).
