docs: clarify dual-memory architecture (fixes #344) (#367)

* docs: clarify dual-memory architecture (fixes #344)

Add two improvements addressing Issue #344:

1. README: add Dual-Memory Architecture section explaining
   Plugin Memory (LanceDB) vs Markdown Memory distinction
2. index.ts: log dual-memory warning on plugin startup

Refs: #344

* Address AliceLJY review comments: restore cli.ts, remove import-markdown reference, restore removed README sections

- Restore cli.ts (was accidentally deleted, all CLI commands preserved)
- Remove import-markdown command reference from dual-memory section (lives in PR #426)
- Restore beta.10 version banner and OpenClaw 2026.3+ badge
- Restore Auto-recall timeout tuning FAQ section

Ref: #367

+## ⚠️ Dual-Memory Architecture (Important)
+
+When `memory-lancedb-pro` is active, your system has **two independent memory layers** that do **not** auto-sync:
+
+| Memory Layer | Storage | What it's for | Recallable? |
+|---|---|---|---|
+| **Plugin Memory** | LanceDB (vector store) | Semantic recall via `memory_recall` / auto-recall | ✅ Yes |
+| **Markdown Memory** | `MEMORY.md`, `memory/YYYY-MM-DD.md` | Startup context, human-readable journal | ❌ Not auto-recalled |
+
+**Key principle:**
+> A fact written into `memory/YYYY-MM-DD.md` is visible in startup context, but `memory_recall` **will not find it** unless it was also written via `memory_store` (or auto-captured by the plugin).
+
+**What this means for you:**
+- Need semantic recall? → Use `memory_store` or let auto-capture do it
+- `memory/YYYY-MM-DD.md` → treat as a **daily journal / log**, not a recall source
+- `MEMORY.md` → curated human-readable reference, not a recall source
+- Plugin memory → **primary recall source** for `memory_recall` and auto-recall
