Skills sync telemetry gains a suspended outcome and unified payload builder

The skills-sync process, which keeps the list of available skills up to date, now builds its telemetry through a single shared function that always includes account_opt_in, trigger, and duration_ms, plus two new fields: suspended_ms (time the process spent suspended or asleep during the round) and tick_late_ms when applicable.

• If a skills-list fetch fails with a timeout, network, or HTTP error, and suspended_ms exceeds 45 seconds, the round now reports its outcome as suspended instead of list_failed.
