feat(cli): add --wait-timeout option to run command

Replace hardcoded 10-minute timeout with configurable --wait-timeout.
Default is no limit, matching the wait command behavior. Extracts
parseDuration to shared utils so both run and wait can use it.

Fixes OUTPUT_SCHEMA_FAILED errors when agents take >10 minutes.
