Plugin marketplace: Update button unresponsive when plugin version is outdated

Description

The Update button in the plugin marketplace detail view is visually present but not clickable/pressable, even when the plugin has a newer version available and the \"Last updated\" timestamp is recent.

Steps to Reproduce

1. Open Claude Code → Customize → (select a plugin from the marketplace)
2. Observe a plugin that shows a recent \"Last updated\" time and has an available update
3. Click the Update button in the top-right corner of the plugin detail view

Expected Behavior

Clicking Update should trigger the plugin update flow.

Actual Behavior

The Update button is unresponsive — it appears enabled visually (not grayed out) but does not react to clicks.
