chore(release): 1.0.1-unstable.20260821055855

[github-actions]

Version bump for 1.0.1-unstable.20260821055855, opened by the release workflow.

The tag v1.0.1-unstable.20260821055855 already names this commit, so the released
package and its label agree. Merging this brings development up
to the released version.

Raised as a pull request rather than pushed directly because
development requires one; a direct push is rejected with GH013
and takes the release down with it.

Closing as superseded — an automated version-bump PR (appinfo/info.xml only) with a newer one already open for this repo. Merging an older bump would move the declared version backwards relative to the newest tag. The tag is unaffected; tags are independent refs.
