BindAlias

Fixed

• MCP: snap screenshots were stale — all screenshots were captured before the alias chain ran, so every snap envelope carried a pre-action frame. Immediate snaps now capture right after the action; deferred snaps capture at expiry on the main thread, ensuring the frame matches the captured state.

Changed

• MCP: each snap screenshot delivered as its own image block — multi-snap responses now return one image block per screenshot instead of bundling everything into a single block, matching the documented per-envelope delivery contract.
