Claros v0.2.2

v0.2.2 — Engine Core

The lifecycle engine now runs end to end.

• Segment-compatible event ingestion (track and identify) with API key auth,
  server-side deduplication, and partitioned event storage
• Contact model with trait merging, conflict recording, and a unified lifecycle
  state machine covering seven states
• Flows defined in plain language and compiled once by an LLM into a
  deterministic execution plan, with a bring-your-own key
• Flow execution: enrollment with priority and re-entry rules, step advancement,
  exit conditions, and engagement depth from incremental counters
• Throttle gate with suppression, frequency caps, and timezone-aware send windows
• Drain and reap workers with crash recovery

Not yet functional: email content generation and actual sending. Messages are
created, throttled, and queued, but no transport exists yet, so nothing leaves
the system.
