/**
 * MemoryProvider
 *
 * An in-memory implementation of IWeaveProvider backed by a plain `Map`.
 * Zero-latency reads/writes, no I/O, no external dependencies.
 *
 * Ideal for:
 *  - Unit tests (fast, isolated, no temp-file cleanup needed)
 *  - Ephemeral sessions where persistence across restarts is not required
 *  - Streaming pipelines that only need within-process memory
