[Bug] Post-install plugin configure dialog: ←/→ still switch tabs instead of cycling userConfig options (2.1.284)

What's Wrong?

The "Configure <plugin>" dialog that opens automatically right after /plugin install (for a plugin whose manifest declares userConfig with options) still has the #97103 behaviour on 2.1.284: pressing ←/→ on an options field switches the tabs of the /plugin tab bar instead of cycling the field's value. The value cannot be changed there at all.

The 2.1.284 changelog says this was fixed ("←/→ change an options field instead of switching tabs"), and it is fixed on the other two screens that edit the same values:

• /plugin → Installed → the plugin → Configure options: ←/→ cycle the value.
• /config: the value can be changed.

So the fix seems to cover those screens but not the dialog shown automatically after install, which is the one every new user of such a plugin sees first.

What Should Happen?

In the post-install configure dialog, ←/→ on a field with options should cycle that field's value, as they now do in /plugin → Configure options.

Steps to Reproduce

1. Create a plugin whose .claude-plugin/plugin.json declares:

``json
"userConfig": {
"github": {
"type": "string",
"title": "GitHub",
"description": "Let the plugin work with GitHub.",
"options": ["on", "off"],
"default": "on"
},
"gitlab": {
"type": "string",
"title": "GitLab",
"description": "Let the plugin work with GitLab.",
"options": ["on", "off"],
"default": "on"
}
}
``

1. Add its marketplace and run /plugin install <plugin>@<marketplace>.
2. The "Configure <plugin>" dialog opens with the first field focused. Press ← or →.
3. The tab bar switches; the field's value stays on.
4. For comparison, open /plugin → Installed → the plugin → Configure options and press ←/→ on the same field: the value changes.

Is this a regression?

No. It is the behaviour reported in #97103, which remains in the post-install dialog after the 2.1.284 fix.
