[BUG]: Simultaneously having --prompt and --session does not auto-run the prompt

[EvanZhouDev]

Description

If you run OpenCode as such:

opencode --session ses_something --prompt "continue."

It doesn't actually put the prompt into the session and continue running.

Plugins

opencode-pty

OpenCode version

1.2.8

Steps to reproduce

1. Start a session, and get its session ID
2. Run opencode --session ses_something --prompt "continue."

Observe that the session just opens, but no prompt is submitted to run.

This issue might be a duplicate of an existing issue. Please check:

• Bug: opencode --continue --prompt does not work #8850: Same bug reported where using --prompt together with a session-continuation flag (--continue instead of --session) does not auto-run the prompt.

If your issue is distinct (e.g., specific to --session vs --continue, or a regression), please add a comment clarifying how it differs.

I suppose my issue is technically specific to --session, but I'm suspecting it's the same root cause!
