v1.3.1 — Stability & Robustness

Fixed

• Memory extraction failures now emit a warning to stderr instead of failing silently, while preserving successful event append semantics.
• Eliminated a latent circular import risk in the memory lifecycle subsystem.
• Improved \MarkdownMemoryProvider\ thread safety for concurrent writes within a single process.
• Clarified documentation for reserved relation event types intended for future persistence.

Quality

• No public API changes.
• No behavioral changes to event sourcing, retrieval, or projections.
• Full regression suite passing (1771 tests).
