schedule: fire --every now by default, add run-once for cron-style triggers (#689)

Interval schedules used to wait the full interval before their first run, which
made `--every 1d` feel broken for fresh schedules. Now `--every` fires
immediately on creation; `--cron` keeps waiting for the next slot. `--no-run-now`
and `--run-now` override the defaults, and the parser rejects redundant combos.

Adds `paseo schedule run-once <id>` to manually trigger a single run without
advancing cadence or recomputing completion. The new `runOnCreate` field and
`schedule/run-once` RPC are additive on the WebSocket schema.
