fix(opencode-local): resolve HOME from os.userInfo() for model discovery

Browse Source 
When Paperclip's server is started via `runuser -u node` (common in
Docker/Fly.io deployments), the HOME environment variable retains the
parent process's value (e.g. /root) instead of the target user's home
directory (/home/node). This causes `opencode models` to miss provider
auth credentials stored under the actual user's home, resulting in
"Configured OpenCode model is unavailable" errors for providers that
require API keys (e.g. zai/zhipuai).

Fix: use `os.userInfo().homedir` (reads from /etc/passwd, not env) to
ensure the child process always sees the correct HOME, regardless of
how the server was launched.
