v3.0.0: Add /mc interactive commands for Telegram/Discord/CLI

New companion plugin (mc-plugin/) registers /mc as a native OpenClaw
slash command with 10 subcommands: state, history, restore, clear,
search, settings, compact, export. All commands work across multiple
agent workspaces and return instant responses (direct file reads,
no model invocation).

+## Interactive Commands (`/mc`)
+
+v3.0.0 adds a companion plugin that registers `/mc` as a native slash command. Works in Telegram, Discord, and anywhere OpenClaw commands are supported.
+
+```
+/mc state              View main agent's working state
+/mc state --all        Overview of all agents
+/mc state tech_geek    View a specific agent's state
+/mc history            List archived sessions
+/mc restore 3          Restore archive #3
+/mc search auth        Search "auth" across all memory
+/mc settings           View plugin settings
+/mc settings maxArchiveCount 30   Update a setting
+/mc compact            Compress oversized state file
+/mc export all         Export all agents' memory to file
+/mc --help             Command reference
+```
+
+The `/mc` plugin reads memory files directly — no HTTP endpoints, no model invocation. Responses are instant.
+
+### Install the command plugin
+
+The `/mc` command plugin is separate from the lifecycle plugin. To install:
+
+```bash
+# Clone (if you haven't already)
+cd ~/.openclaw/projects
+git clone https://github.com/dtzp555-max/memory-continuity.git
+
+# The mc-plugin is bundled in the mc-plugin/ directory
+cp -r memory-continuity/mc-plugin ~/.openclaw/projects/mc-plugin
+mkdir -p ~/.openclaw/extensions/mc
+cp ~/.openclaw/projects/mc-plugin/* ~/.openclaw/extensions/mc/
+```
+
+Then add to `openclaw.json`:
+```json
+{
+  "plugins": {
+    "allow": ["memory-continuity", "mc"],
+    "entries": {
+      "mc": { "enabled": true }
+    },
+    "installs": {
+      "mc": {
+        "source": "path",
+        "sourcePath": "~/.openclaw/projects/mc-plugin",
+        "installPath": "~/.openclaw/extensions/mc"
+      }
+    }
+  }
+}
+```
+
+Restart the gateway and `/mc --help` should work.

 ## Configuration
 
 The plugin works with zero configuration. Optional settings in `openclaw.json`:
