When enabled, strfry keeps ALL versions of replaceable events (kinds 0, 3, 10000-19999, 30000-39999) instead of deleting old versions when newer ones arrive. This is useful for: - Audit trails - Historical analysis - Compliance requirements Enable with env var: STRFRY_RETAIN_REPLACED_EVENTS=true
The previous implementation could cause index corruption by storing older incoming events. This fix: 1. When NEWER event arrives: keep old event in storage (audit) but still update replace index to point to new event. NIP-01 queries return only latest; old events queryable by ID. 2. When OLDER event arrives: reject it (even in audit mode) to prevent index corruption. Use external JSONL audit log to capture these. This preserves NIP-01 compliance while enabling audit trail for events that were superseded by newer versions.

Summary
This PR adds an optional ingest-time event-payload compression path that keeps default behavior unchanged.

For installations prioritizing storage and bandwidth efficiency, immutable signed event JSON is a strong candidate for compress-once semantics. This provides a low-risk, opt-in path while preserving current defaults.
Compatibility
0x00,0x01) remain readable.0x02records decode transparently for reads.Notes
I could not run a full local build here because this environment is missing strfry's
golpebuild include (golpe/rules.mk). The change is intentionally scoped to payload encode/decode logic to simplify review and testing.
