/plugin uninstall shows "Enabled <plugin>" confirmation instead of uninstall message

Description

When uninstalling a plugin through the /plugin menu, the confirmation message incorrectly reads:

✓ Enabled pr-review-toolkit. Run /reload-plugins to apply.

It should say "Uninstalled" (or similar). The uninstall itself works — the entry is removed from ~/.claude/plugins/installed_plugins.json — but the message is misleading and made me think I had accidentally re-enabled the plugin.

Reproduction

1. Install a plugin (e.g. pr-review-toolkit@claude-plugins-official)
2. Open /plugin and choose Uninstall
3. Observe the confirmation message

Expected

✓ Uninstalled <plugin>. Run /reload-plugins to apply.

Actual

✓ Enabled <plugin>. Run /reload-plugins to apply.

Environment

• Claude Code: 2.1.110
• OS: Linux (WSL2, Ubuntu)

Additional notes

The cache directory under ~/.claude/plugins/cache/claude-plugins-official/<plugin> is also left on disk after uninstall — minor, but worth cleaning up as part of the uninstall flow.
