"""Append the co-op credit-pack hint to LiteLLM's hardcoded budget-exceeded messages.

Run at BUILD time (the runtime rootfs is read-only under Cloudron). Non-fatal:
if the target file or message strings are missing (e.g. after an upstream
version bump moves or rewrites them), it prints a warning and exits 0 so the
build — and the gateway — still succeeds. The hint is a nice-to-have, never a
reason to take the gateway down.
