HPC Confirmation Gate: By default, HPC tasks pause at
PENDING_REVIEWafter local preprocessing completes, so users can verify structures and parameters before spending HPC resources. Users confirm via the frontend "Confirm & Submit" button (per-task or "Confirm All"). To skip this gate, callwf.submit(auto_submit=True).HPC Confirmation Required: Before calling
wf.submit()orcatgo_workflow_engine(action="submit"), you MUST ask the user which HPC cluster to use and confirm job parameters (partition,account,walltime,ntasks). These can be set per-task viaadd_taskparams. Never submit without user confirmation.

One-shot recipes for adding, deleting, moving, and replacing individual atoms in the active CatGo viewer structure. Use whenever the user asks to "add an atom", "delete atoms", "remove this atom", "move atom N", "replace H with Li", or any single-atom edit — including "add a hydrogen on top of atom 12" / "delete atoms 5–9" / "swap the oxygen at site 3 for fluorine". Skips the discovery loop (no need to list structure tools or check adsorption sites first); goes straight to the matching `catgo_structure` action.
