 ### Fixes
 
+- Build/plugin-sdk bundling: bundle plugin-sdk subpath entries in one shared build pass so published packages stop duplicating shared chunks and avoid the recent plugin-sdk memory blow-up. (#45426) Thanks @TarasShyn.
 - Browser/existing-session: accept text-only `list_pages` and `new_page` responses from Chrome DevTools MCP so live-session tab discovery and new-tab open flows keep working when the server omits structured page metadata.
 - Ollama/reasoning visibility: stop promoting native `thinking` and `reasoning` fields into final assistant text so local reasoning models no longer leak internal thoughts in normal replies. (#45330) Thanks @xi7ang.
 - Cron/isolated sessions: route nested cron-triggered embedded runner work onto the nested lane so isolated cron jobs no longer deadlock when compaction or other queued inner work runs. Thanks @vincentkoc.
