Additional Context

This is an update to an existing community catalog entry, not a new extension submission. Please preserve the existing entry identity (id: preview) and update the catalog metadata for v1.1.0.

[bigsmartben]

Post-submission verification: installed the v1.1.0 release ZIP in a fresh Spec Kit project with \specify extension add preview --from https://github.com/bigsmartben/spec-kit-preview/archive/refs/tags/v1.1.0.zip --force. The CLI reported \Spec Kit Preview (v1.1.0)\ and listed all six preview commands.
