predicator 9.2.0 and statifier_ui 0.4.0 are published, so both
interim git-ref pins come out and `mix hex.build` accepts the
package again. `override: true` goes with the refs: it existed
only to reconcile a git-ref divergence that no longer exists.

The predicator floor stays at `~> 9.0` rather than rising to
9.2. Every predicator module this package names shipped in
9.0.0; the 9.2 module is `Predicator.Simple`, which only
statifier-ui calls, and statifier-ui is optional here and
requires `~> 9.2` itself. A host taking the editor is driven to
9.2 transitively; one taking this package alone needs 9.0.

statifier_ui stays optional and stays inside `live_view_dep/0`,
so the headless tree is unchanged (ADR-0005 decision 1).
