TODO: Implement full replay engine with event stream processing

• Type: TODO
• Location: src/cli/replay.ts:3
• Original text: TODO(roadmap): Phase 4 — Full replay engine: feed stored event stream through encounter generator

Task Description

The current agentguard replay CLI command exists but lacks the full replay engine. The implementation needs to:

1. Read stored event streams from JSONL files (.agentguard/events/<runId>.jsonl)
2. Feed events through the encounter generator to reconstruct the governance session
3. Support playback of the full kernel loop (propose → normalize → evaluate → execute → emit) from persisted events

This is a prerequisite for deterministic replay (#seeded RNG) and the replay comparator. The existing src/cli/replay.ts is a stub referencing this work.

Related ROADMAP items

• Phase 3: CLI replay command (done) — this extends it with the full engine
• Phase 3: Deterministic replay with seeded RNG (depends on this)
• Phase 3: Replay comparator (depends on this)
