fix node24 PATH propagation and improve action logging (#381)

Add node24 binary directory to PATH in action entry point so spawned
processes (pnpm, npm, etc.) resolve to the correct node version instead
of the runner's default v20. Improve delegate task result logging with
success/failure status and summaries. Use collapsible log groups for
dependency install output instead of raw streaming.
