fix(plugins): preserve sibling npm installs

Run npm install from the managed npm-root manifest so sequential @openclaw/* plugin installs preserve siblings on disk.

Fixes #76571.
Thanks @byungskers and @crpol.

 - Active Memory: apply `setupGraceTimeoutMs` to the embedded recall runner as well as the outer prompt-build watchdog, so very-cold first recalls keep the configured setup grace end-to-end. (#74480) Thanks @volcano303.
 - Plugins/tools: keep disabled bundled tool plugins out of explicit runtime allowlist ownership and fall back from loaded-but-empty channel registries to tool-bearing plugin registries, so Active Memory can use bundled `memory-core` search/get tools even when `memory-lancedb` is disabled. Fixes #76603. Thanks @jwong-art.
+- Plugins/install: run `npm install` from the managed npm-root manifest so installing one `@openclaw/*` plugin preserves already installed sibling plugins instead of pruning them. Fixes #76571. (#76602) Thanks @byungskers and @crpol.
 - Channels/QQ Bot: resolve structured `clientSecret` SecretRefs before QQ token exchange, expose the QQ Bot secret contract to secrets tooling, and reject legacy `secretref:/...` marker strings. (#74772) Thanks @xialonglee.
 - Plugins/externalization: keep official ACPX, Google Chat, and LINE install specs on production package names, leaving beta-tag probing to the explicit OpenClaw beta update channel. Thanks @vincentkoc.
 - CLI/doctor: keep missing-plugin repair from overriding official catalog metadata with runtime fallbacks, so ACPX repairs preserve the official npm spec during the externalization rollout. Thanks @vincentkoc.
