Feature request: Add the ability for models to request changing modes from plan to build #1912

Hey opencode team,
I think it would be super helpful if similar to Claude Code, Kilo code etc, if opencode could let the models prompt the user when it would like to switch modes. That way, after writing out a plan, there would be a prompt from opencode asking you if you want to implement the plan. Right now, it is a little bit awkward because the LLM will output a plan and ask you if you're ready to implement it, then the user has to remember to switch modes then send a confirmation message.
