When a report would take the report files past DATA_DIR_MAX_BYTES, reportbuf now deletes the oldest report files until it fits, and does the same at start when files left by an earlier run are already past it. A file joins the files that may be deleted, at its place by name, only once it is completely written, so a file still being written is never deleted. A report is refused with 507 only when the reports waiting to be written fill the cap on their own, and then no file is deleted. The reports of a failed write stop counting, and the part of its file written is removed. A file whose deletion fails keeps counting; one already deleted by hand counts as freed. Model: opus-5-5
