Hello! I noticed HostError already implements a summary() method in host_error.rs. Before I continue, should this issue update the existing implementation to the new 80-character Tier 1 format, or is there another summary() implementation you intended me to modify?

Thanks for confirming. Before I update summary(), should the implementation simply truncate the existing summaries to the new 80-character Tier 1 format, or would you prefer introducing dedicated short summaries (e.g. [BUDGET] CPU Exceeded) instead of truncating the existing descriptive text?
