The public UHD keydb (fvonline) is ~62 MiB and growing, leaving only ~2 MiB under the old 64 MiB ceiling — updates would start failing as it grows. 128 MiB restores years of headroom while still bounding a decompression bomb. Both cap sites (keydb.rs download/save, keydb_format.rs on-disk load) bumped; the unrelated MKB cap in online.rs is untouched.
