Digest 2.12 is a CLI release.

## digest diff

Compares your local configuration with what is deployed and prints the change as a unified diff. Nothing is applied. It is the same computation `digest apply` performs, split out so you can read it first.

```diff
$ digest diff
--- deployed
+++ local
@@ webhooks @@
-  retries: 3
+  retries: 5
+  backoff: exponential
```

## digest validate

Checks the configuration file against the schema and reports every error, not just the first. Runs automatically before apply.

## Login

The browser flow now returns to the terminal in one step. The device-code flow remains for machines without a browser.

## Fixed

- `apply` exited 0 on a partial failure (#4380).
- Very long config files were truncated in the error output (#4391).
