fix: auto-configure idleTimeoutSeconds=0 to prevent tool-call timeouts

setup.mjs now sets agents.defaults.llm.idleTimeoutSeconds=0 in
openclaw.json during installation. Without this, OpenClaw's default
60s idle timeout kills Claude connections during tool use (Bash, Read,
etc.), causing exit 143 errors and stuck sessions.

Also adds troubleshooting section to README. Bump to v3.2.1.
