Security
Resolves all open Dependabot advisories by bumping the example module's
transitive dependencies golang.org/x/net and golang.org/x/image to
v0.38.0.
These were development-only dependencies pulled in by the examples' GUI
libraries. The importable hotkey module — which depends only on
golang.design/x/mainthread — was never affected, and its code is unchanged
from v0.6.0.
Full changelog: v0.6.0...v0.6.1
