feat: let ACP client expose the input/output properly

[validatedev]

What does this PR do?

Fixes#10998.

Old behavior: we sent a tool_call at pending with kind: "execute". As the tool ran, updates carried the content plus a completed rawOutput. Zed relied on kind: "execute" to render the blue "run command" box, but the actual command (rawInput) only appeared after completion, so you couldn't see what was running.

New behavior: the first tool_call now reflects the tool part's actual status (e.g. in_progress when the tool is already running on first observation) and carries the full rawInput — including the resolved working directory for bash — so Zed can show the command and where it's running before output lands. Subsequent tool_call_updates fill in streaming content and the final rawOutput (stdout/stderr). kind is set to other (not execute), which removes the blue run-box styling and instead exposes rawInput/rawOutput as collapsible panels.

How did you verify your code works?

By running Zed's ACP inferface via:

 "OpenCode (ACP Dev)": {
"type": "custom",
"command": "bun",
"args": [
"run",
"--cwd",
"/Users/validate/Developer/personal/opencode/packages/opencode",
"--conditions=browser",
"./src/index.ts",
"acp",
],
"env": {},
},

Can you explain the changes, it looks like quite a bit

What are we waiting for? This needs to be fixed

[validatedev]

@rekram1-node@nexxeln@thdxr waiting to be reviewed, just fyi.

[soar]

How is it going here?

[kian1991]

Yeah pushing this. I am checking in every day, i guess there are just too many open PRs.

Cant wait for this to get merged. The whole oc acp is now useless in Zed since you cant read the command that it runs. Not hating, but would just love to use this harness in Zed :)

[spotlesscoder]

please prioritize this

[makoMakoGo]

when to merge? the current opencode acp is totally not useable. I cant bear it anymore. why the opencode maintainers even didn't leave any reviews. I want to say that opencode is totally dog shit. 😡

[kian1991]

Bumping here as well please review

[soar]

I assume this will never be fixed

Hello, any progress on this? Just found the original issue and it seems to have been auto-closed due to inactivity. OpenCode maintainers, can you please review this and merge it? thanks!

[validatedev]

Done and merged to dev thanks to @nexxeln :)
