_⚠️ Potential issue_ | _🟡 Minor_

**Guard against `None` duration in format string.**

Similar to the pipeline, `result.duration` can be `None` on early failures, causing a `TypeError` when formatting.

```diff
-        click.echo(f"   Duration: {result.duration:.1f}s")
+        if result.duration is not None:
+            click.echo(f"   Duration: {result.duration:.1f}s")
```

```
In `@packages/core/ai_content_platform/vimax/cli/commands.py` at line 77, The
duration formatting call can raise TypeError when result.duration is None;
update the click.echo that prints "Duration" to guard against None (use a
conditional expression or helper like duration_str = f"{result.duration:.1f}s"
if result.duration is not None else "N/A") and then echo duration_str instead of
directly formatting result.duration; reference the click.echo line that
currently uses f"   Duration: {result.duration:.1f}s" and the result.duration
variable when making the change.
