feat(v0.3.0): Event Orchestrator skill

- New system-event-orchestrator skill with hook registry, cron registry, and tier classifier

- Three dispatch tiers: :reflex (no LLM), :cognition (light), :reasoning (full)

- Org-mode timestamp parsing for repeat patterns (+1w, +1d, +1m)

- Registers on heartbeat via defskill, dispatches due cron jobs

- Fix all remaining harness-log → log-message references across org files
