v0.32.4

Patch release fixing a dreamer prompt-integrity bug on Pi (#232).

Fixed

Dreamer tasks could lose their system prompt on model-fallback retries (#232). The retry executor reused one request body across attempts; a failing first attempt could consume the body's system field, and on Pi the retried child then spawned without --system-prompt, letting Pi substitute a persisted user-mode prompt. Classify-memories was the visible victim (a zero-tool task whose correctness is entirely its system prompt). Every retry attempt now carries a fresh snapshot of the original request body, on both Pi and OpenCode.
Zero-tool dreamer children refuse to run without a system prompt. A classifier or reviewer spawned with an empty prompt can only produce garbage, so the Pi runner now fails these runs as transient task errors before the child process is created, instead of silently running with whatever prompt Pi has persisted.
