TUI /status dialog shows full file path instead of plugin name on Windows

Description

On Windows, file:// plugins in the /status dialog display the full file path instead of just the plugin name.

What happened:
The plugin list shows C:\Users\Administrator\ instead of rtk:

2 Plugins
• C:\Users\Administrator\
• oh-my-openagent @next

Root cause:
In packages/tui/src/component/dialog-status.tsx (line 23):

const path = fileURLToPath(value)
const parts = path.split("/")  // only splits on /

fileURLToPath() returns C:\Users\Administrator\.config\opencode\plugins\rtk.ts on Windows. Since there's no /, split("/") returns a single-element array, and pop() returns the entire path string.

How to fix:
Replace split("/") with split(path.sep) from the path module.

Affected:
Only the TUI status dialog display for file:// plugins. No functional impact.

Note: Issue #34141 reported this same bug but was closed without
the fix being merged. Two PRs (#33375, #34183) attempted to fix it
but were also closed. The bug still exists in the current dev branch,
so I'm re-reporting it.
