## Summary
- add commands for setting search aliases and description when in
subgraph
- in future we can add these fields to the dialog when publishing a
subgraph
- map workflow extra metadata on save/load from from/to subgraph node to
allow access via `canvas.subgraph.extra`
## Changes
**What**:
- new core commands for Comfy.Subgraph.SetSearchAliases &
Comfy.Subgraph.SetDescription to be called when in a subgraph context
- update Publish command to allow command metadata arg for name
- update test executeCommand to allow passing metadata arg
## Review Focus
- When saving a subgraph, the outer workflow "wrapper" is created at the
point of publishing. So unlike a normal workflow `extra` property that
is available at any point, for a subgraph this is not accessible.
To workaround this, the `extra` property that exists on the inner
subgraph node is copied to the top level on save, and restored on load
so extra properties can be set via `canvas.subgraph.extra`.
- I have kept the existing naming format matching `BlueprintDescription`
for `BlueprintSearchAliases` but i'm not sure if the description was
ever used before
