`/resume` only shows named sessions, `claude --resume` shows all

Description

/resume inside an active Claude Code session only lists named sessions, while claude --resume from the terminal lists all recent sessions (named + unnamed).

Steps to Reproduce

1. Have several unnamed previous sessions and one named session
2. Start a new Claude Code session with claude
3. Type /resume — only the named session appears
4. Exit and run claude --resume from the terminal — all sessions (named + unnamed) appear

Expected Behavior

/resume inside a session should show the same list of sessions as claude --resume from the terminal, including unnamed sessions.

Actual Behavior

/resume inside a session only shows named sessions.

Environment

• Claude Code v2.1.71
• macOS (Darwin 25.3.0)
