Adding Formative Memory to the Skills & Tools section (memory layer for OpenClaw agents).

A biologically-inspired OpenClaw memory plugin:

• Recall — hybrid BM25 + embedding search with strength-weighted ranking and one-hop association expansion (weighted bidirectional links between memories).
• Evaluate — attribution tracks which surfaced memories actually influenced the reply; only those are reinforced.
• Capture — explicit memory_store or chain-of-thought auto-capture that filters durable facts.
• Consolidate — nightly "sleep" loop: decay, prune, LLM-merge. All mutation deferred here, so live chat stays read-only and fast.

Differs from the other memory entries already on the list (mem0, memU, MemOS, MoltBrain, openclaw-supermemory, etc.) mainly through provenance-based reinforcement (memory strength reflects demonstrated influence on the reply, not just retrieval frequency) and deferred mutation (all writes batched into nightly consolidation).

Single-file SQLite + FTS5 + sqlite-vec — no external services. Content-addressed (SHA-256) memory objects make duplicates structurally impossible.

Happy to adjust wording or section placement.
