fix(client): add request timeout to get_path() to prevent hanging on …

[zeekhuge]

Description

This PR addresses an issue where the Neovim plugin becomes unresponsive when multiple opencode --port processes are running and one or more are stopped/unresponsive.

Problem

When I would open quite a few opencode instances (using opencode --port), some of the Nvim instance would become unresponsive to the Ctrl-a command.

On further investigation, I found that: the plugin discovers OpenCode servers by querying each server's /path endpoint. The curl command uses --connect-timeout 1, which only limits TCP connection time. If a process is stopped (e.g., via Ctrl+Z), the TCP socket still accepts connections but never responds, causing curl to hang indefinitely.

The current solution I use is kill $(pidof opencode) and then restart all of them. This works, but is a super productivity kill.
This PR is to bring in better support for the same.

Solution

Add a --max-time to the curl commands for the /path query.
