Arclet-CAD (07egta)MCADConfidence: Medium

The PR adds a read-only inspect_state call returning the document id and revision, and makes MCP batches carry if_revision, so a batch built on stale state gets rejected with a stale_state code and makes no edit. It also detects when the document changed during a multi-call inspection.
