Four-layer local memory system plugin for OpenClaw — auto-captures, structures, and profiles conversational knowledge using local LLM + SQLite vector search (L0→L1→L2→L3 pipeline)

/**
 * NoopQuotaReporter — default (open-source) quota reporter.
 *
 * Behaviour:
 *   - fetchQuota() returns null → QuotaManager treats this as "unlimited",
 *     so every checkMemoryQuota / checkCreditQuota call passes.
 *   - reportUsage() is a no-op (no remote billing in open-source builds).
 *
 * Use this in standalone / self-hosted deployments where there is no
 * billing system to report into.
