### Builds

Voltage's release workflow sets `BUZZ_GPUI_VOLTAGE=1`. These packages enable
Remote workspaces and place `buzz-backend-relay` beside the app executable.
The package checks run the bundled provider's credential-free `info` operation.
For a local Voltage package, set this variable before running its package script.
On Windows, build first with `bash scripts/build-package.sh -p buzzd`.

The Build workflow makes all of these packages. It runs by hand, for pull
requests that change it, and for `v*` tags, which also attach the packages
to a GitHub release.

Match the desktop’s complete info validation.

If a packaged provider adds an unknown top-level field or advertises more than 32 operations, this check passes but the desktop rejects the provider. The desktop also rejects non-string operation entries. Apply those constraints here so the release check cannot certify that response. (github.com)

17 - 20:
Update the info validation in the remote-provider check to match the desktop’s
complete top-level field and operation constraints: reject unknown top-level
fields, operation arrays with more than 32 entries, and non-string operation
entries. Preserve the existing required-field and required-operation checks,
using the desktop validation as the source of truth.
