Feature Request: Allow status line position customization (below input box)

Feature Request

Summary:
Allow users to configure the display position of the status line, specifically to show it directly below the context input box.

Current behavior:
The status line is fixed at the bottom footer of the Claude Code UI. The statusLine setting in settings.json only controls the content displayed, not its position.

Desired behavior:
Provide an option to display the status line (or a subset of it, such as context usage) directly below the input box — making it immediately visible without looking away from the area where the user is actively typing.

Use case:
Users who monitor context window usage (e.g., via a progress bar showing percentage used) would benefit from seeing this information adjacent to their input area, enabling faster reaction when the context is nearly full.

Proposed setting (example):

"statusLine": {
  "type": "command",
  "command": "bash ~/.claude/statusline-command.sh",
  "position": "below-input"
}

Environment:

• Claude Code CLI (macOS)
