`--prompt` is ignored when combined with `--session --fork` in TUI mode

[raine]

Description

When launching opencode in TUI mode with --session <id> --fork --prompt "...", the session is forked correctly but the prompt is never sent as a message.

Reproduction:

# 1. Create a session, note the session ID
opencode

# 2. Fork it with a prompt - prompt is ignored, but you can see if you press arrow up
opencode --session ses_xxxx --fork --prompt "hello"

Expected: The forked session should open with "hello" automatically sent as the first new user message.

Actual: The forked session opens but no message is sent. The --prompt flag is silently ignored.

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

• --prompt option is ignored when used with --session #14787: --prompt option is ignored when used with --session — nearly identical bug report (closed), though your issue adds the --fork flag specifically. If the fix for --prompt option is ignored when used with --session #14787 didn't cover the --fork combination, this may be a regression or a related but distinct case.
