/branch command outputs incorrect resume command — missing --resume flag

Bug Description

The /branch command outputs a resume command that doesn't work:

Branched conversation. You are now in the branch.
To resume the original: claude -r 117e1b95-ba8f-4e41-a7e4-58422f516035

But running it produces an error:

$ claude -r 117e1b95-ba8f-4e41-a7e4-58422f516035
Error: --session-id can only be used with --continue or --resume if --fork-session is also specified.

Expected Behavior

The output should include --resume (or --continue) flag, e.g.:

To resume the original: claude --resume -r 117e1b95-ba8f-4e41-a7e4-58422f516035

Or:

To resume the original: claude --continue 117e1b95-ba8f-4e41-a7e4-58422f516035

Steps to Reproduce

1. Start a Claude Code session
2. Run /branch
3. Copy the "To resume the original" command from the output
4. Run it in terminal
5. Get error: --session-id can only be used with --continue or --resume if --fork-session is also specified.

Environment

• Claude Code: 2.1.84
• Platform: macOS Darwin 25.3.0
• Shell: zsh
