chore(scheduler): skip agents whose data sources aren't granted (#128)

Check getEligibleAgentIds per user in runCycle before calling
computeAndStore — agents without consented data sources, silenced by
active context, or disabled via preference are skipped rather than
computed unconditionally. Eligibility check failure skips the whole
user (fail-closed). Skipped count added to cycle-complete log line.
