Feature request: option to hide PR number from input prompt

Description

The input/permission prompt line in Claude Code CLI shows the PR number for the current branch:

▸▸ bypass permissions on (shift+tab to cycle) · PR #1220

There is currently no way to hide the · PR #XXXX part.

Requested behavior

A setting like showPRInPrompt: false in settings.json (or similar) to hide the PR number from the input prompt line.

Why

• The PR number is already visible in the custom status line (via gh pr view cache) and in the terminal tab/title for users who configure it.
• Having it in the prompt line adds visual clutter without additional value for these users.
• All other prompt-adjacent elements (status line, attribution) have configuration options, but this one does not.

Current workarounds

None found. Checked:

• settings.json schema (180+ properties) — no relevant flag
• /config — no option
• Environment variables — none
• prUrlTemplate — changes URL target, doesn't hide
• attribution.pr — controls PR description attribution, not the prompt display
