fix(hooks): avoid stale active-memory startup fallback

CHANGELOG.md

@@ -60,6 +60,7 @@ Docs: https://docs.openclaw.ai
 - ACP/sessions_spawn: honor explicit `model` overrides for ACP child sessions instead of silently falling back to the target agent default model. (#70210) Thanks @felix-miao.
 - Diffs/viewer: re-read remote viewer access policy from live runtime config on each request, so toggling `plugins.entries.diffs.config.security.allowRemoteViewer` closes proxied viewer access immediately instead of waiting for a restart. Thanks @vincentkoc.
 - Memory/LanceDB: stop resurrecting removed live `memory-lancedb` hook config from startup snapshots, so deleting or disabling the plugin entry shuts off auto-recall and auto-capture without a restart. Thanks @vincentkoc.
+- Active Memory: stop reviving removed live `active-memory` config from startup snapshots, so removing the plugin entry turns the hook off immediately instead of waiting for a restart. Thanks @vincentkoc.
 - Agents/subagents: drop bare `NO_REPLY` from the parent turn when the session still has pending spawned children, so direct-conversation surfaces such as Telegram DMs no longer rewrite the sentinel into visible fallback chatter while waiting for the child completion event. (#69942) Thanks @neeravmakwana.
 - Plugins/install: keep bundled plugin dependencies off npm install while repairing them when plugins activate from a packaged install, including Feishu/Lark, Browser, and direct bundled channel setup-entry loads.
 - CLI/channels: skip and cache bundled channel plugin, setup, and secrets load failures during read-only discovery, so one broken unused bundled channel cannot crash `openclaw status` or bootstrap secret scans.
