Merge refactor-sans-io: converge next bloom onto v1-sans-IO

Forward-merge the master-line bloom relocation into the next line,
discarding next's v1.5 bloom draft (RLE codec, XOR-diff delta,
FilterNack/0x21, adaptive sizing) and converging both lines onto the
identical proto/bloom v1-sans-IO module. This is a deliberate,
temporary wire regression on the next line: the v2 bloom is rebuilt
fresh, sans-IO from day one, on both lines later. Nothing outside the
bloom feature depended on the v1.5-specific surface. proto/bloom is now
byte-identical across both integration lines.
