Fixed
- The
engine.getChatHistoryplugin capability (added in 0.8.5) now reaches sandboxed plugins. It was wired only into the host-side context, not the plugin-worker bridge, so a sandboxed plugin'sctx.engine.getChatHistorywasundefinedand the call failed silently. It is now bridged through the worker capability + router like the other engine reads. Historical messages from the whatsapp-web.js engine also carry location coordinates and quoted-message references now, matching the live message path (previously a backfilled location rendered empty and replies lost their thread link).
