* fix(set_layout): default to HUG sizing when enabling auto-layout
When `set_layout` transitions a frame from `layoutMode: 'NONE'` to
auto-layout, it now sets `primaryAxisSizingMode` and
`counterAxisSizingMode` to `'AUTO'` (which maps to HUG internally).
Previously these remained at `'FIXED'`, causing the frame to keep its
original dimensions instead of shrinking/growing to fit children. This
made `h="hug"`, `justify="end"`, and `grow={1}` appear broken when
containers were created via the `set_layout` MCP tool (as opposed to
the JSX `render` path, which already defaulted to HUG).
The fix only applies when `direction` is provided and the frame was
previously in `layoutMode: 'NONE'` — updating spacing or alignment on
an existing auto-layout frame does not reset sizing modes.
