[DOCS] Settings page missing `prUrlTemplate` setting for custom footer PR links

Documentation Type

Missing documentation (feature not documented)

Documentation Location

https://code.claude.com/docs/en/settings

Section/Topic

Available settings and the terminal footer PR link behavior documented under PR review status

Current Documentation

The settings page currently documents nearby pull-request customization settings:

| attribution | Customize attribution for git commits and pull requests. See [Attribution settings](#attribution-settings) | {"commit": "🤖 Generated with Claude Code", "pr": ""} |

And the interactive-mode page documents the footer PR link itself:

When working on a branch with an open pull request, Claude Code displays a clickable PR link in the footer (for example, "PR #446"). The link has a colored underline indicating the review state: Cmd+click (Mac) or Ctrl+click (Windows/Linux) the link to open the pull request in your browser. The status updates automatically every 60 seconds.

No documentation currently exists for a prUrlTemplate setting or for configuring that footer PR badge/link to open a custom code-review URL instead of github.com.

What's Wrong or Missing?

Changelog v2.1.119 added a user-facing prUrlTemplate setting, but the docs do not describe it anywhere. Users currently have no documented way to learn that the footer PR badge can target a custom review URL, what setting key enables it, or how to configure the template value.

Suggested Improvement

Add prUrlTemplate to the settings documentation with a short example showing how it maps the current branch's PR badge to a non-GitHub review URL. The docs should explain the expected template format/placeholders and note in the PR review status section that the footer link can use this configured custom destination instead of always opening GitHub.

Impact

Medium - Makes feature difficult to understand
