Kill the dual-boot FN-7956 class hang for in-process agent tools:
- setHostTaskStore/clearHostTaskStores inject the live dashboard/serve/daemon store
- Prefer host-injected store over createTaskStoreForBackend; race-safe with external overwrite
- fn_skills_install kills npx on abort/timeout so orphan install processes cannot outlive the turn
- Raise budgets for task plan, experiment finalize, and mission backfill
- Hard-cap import/browse batch size at 50 (GitHub + GitLab)
