--name flag does not display TUI session badge

Description

The --name CLI flag sets the session name in metadata (visible in /resume picker and in the session JSONL as customTitle) but does not display the session name badge in the bottom-right corner of the TUI.

The /rename slash command sets the same customTitle field AND displays the badge. Expected behavior: --name should also display the badge.

Steps to reproduce

1. Launch Claude Code with --name: claude --name myname
2. Observe: no session badge in the bottom-right of the TUI
3. Type /rename myname in the same session
4. Observe: cyan badge appears in the bottom-right

Expected behavior

--name myname should display the same TUI badge as /rename myname.

Evidence

Session JSONL confirms --name correctly writes {"type": "custom-title", "customTitle": "myname"} as the first record. The data is there, just not rendered in the TUI.

Environment

• Claude Code (latest, installed via CLI)
• macOS 15.7.4 (Sequoia), Apple M4
• Terminal: Ghostty
