rprompt block no longer renders in oh-my-posh status line

Description

The rprompt block type in oh-my-posh themes no longer renders in Claude Code's status line. This was working prior to the latest update.

Steps to reproduce

1. Use an oh-my-posh theme with an rprompt block, e.g.:

{
  "type": "rprompt",
  "segments": [
    {
      "type": "text",
      "style": "plain",
      "foreground": "#d3d7cf",
      "template": "─╯"
    }
  ]
}

1. The left-side prompt (╰─) renders correctly, but the right-side rprompt (─╯) does not appear.

Expected behavior

The rprompt block should render on the right side of the second prompt line, completing the box-drawing frame:

╭─[ segments ]───────────────────────[ right segments ]─╮
╰─                                                    ─╯

Actual behavior

Only the left side renders:

╭─[ segments ]───────────────────────[ right segments ]─╮
╰─

Environment

• Claude Code version: 2.1.37
• Previous working version: pre-2.1.37 (likely 2.1.34 or 2.1.36)
• oh-my-posh version: 29.2.0
• Shell: zsh
• OS: macOS (Darwin 25.2.0)
• Terminal: iTerm 3.6.6

Notes

• The same theme renders correctly in a regular terminal (outside Claude Code)
• The rprompt block is documented and supported by oh-my-posh for zsh: https://ohmyposh.dev/docs/configuration/block
