Copying assets between artifacts is built with UI toasts, gated behind capability flags.

Artifacts now support copying another artifact's assets via copy_from in sessions where that capability is available. Where it isn't available, a new error message clarifies that asset: true can be used instead with a local file_path. A UI toast now reports "copied N asset(s) into the artifact" for asset_copy results, and new frozenCopyFrom / frozenMultiFile flags were added to artifact runtime state.
