zenchantlive ab051952bd feat(logic): establish derived-activity engine and agent-session protocols
Today we reached a major architectural conclusion: project history shouldn't be stored, it should be derived. We rejected the overhead of a separate SQLite event store in favor of an O(N) snapshot-diffing engine that computes human-readable narratives directly from the issues.jsonl source of truth.

Key Triumphs:
- Implemented O(N) diffing algorithm in src/lib/snapshot-differ.ts that transforms raw JSONL into 16 distinct social event types.
- Engineered a file-based persistence layer (src/lib/activity-persistence.ts) to solve the 'Next.js HMR Wiped My Memory' bug, ensuring project heartbeat survives server restarts.
- Developed the agent-session data model that unifies Beads, Activity, and Cross-Agent Mail into a single 'Mission' context.

Raw Honest Moment:
We struggled for over an hour with 'missing history' before realizing that development-mode reloads were purging our in-memory buffers. The shift to a file-backed ring buffer was a reactive pivot that became a core project strength.
