fix(plugin): normalize event session ids

Handle OpenCode session events that carry the session ID under properties.info.id or properties.info.sessionID so background tasks and continuation hooks do not miss idle/error/delete events. Add regression coverage for nested session.idle events completing background tasks and waking continuation hooks.
