Temporarily retire broken StreamVault package

[christopherklint97]

Problem

The current StreamVault.wgt release embeds http://10.1.0.200:3002 as its backend URL. That is a private address from the build environment, so Apps2Samsung users outside that network receive Failed to fetch. The widget also requires a separate self-hosted backend, which the catalog description did not mention.

Change

• Set enabled: false so the broken artifact is no longer distributed.
• Clarify the self-hosted backend requirement in the retained manifest.

This can be re-enabled after Patrick publishes a widget built from christopherklint97/streamvault#37’s fix without an embedded build-host address. The release owner has been notified at PatrickSt1991/streamvault#39.

Verification

• JSON parses and validates against packages.schema.json.
• Structural checks pass: 51 manifests and 60 unique output names.
• scripts/build-manifests.sh could not run locally because this host lacks jq; repository CI will run it.
