fix(plugin): add noopPrefixes to prevent gateway restart loop

OpenClaw's reload watcher classifies all `plugins.*` config changes as
requiring a gateway restart. The plugin loader updates resolvedAt and
installedAt timestamps in openclaw.json on every startup for
npm-installed plugins, causing an infinite restart loop.

Declare `noopPrefixes: ["plugins.installs.botschat"]` so the reload
watcher ignores install metadata changes. This is a defense-in-depth
fix alongside the upstream OpenClaw PR (openclaw/openclaw#41007).

Bump version to 0.1.20.
