docs/FORMAT.md now says a .mf is always a whole file, readers ignore
fields they do not know, and paths are compared byte for byte with no
Unicode normalization. Deterministic Serialization describes what the
writer does: entry order, protobuf encoding, what each entry holds, how
a time is written, zstd settings and how the UUID is chosen, and no
longer claims two runs give the same bytes without --seed or with
--include-timestamps. A signed test vector made once by the code, with a
key used for nothing else, is checked in as
mfer/testdata/test-vector.mf, shown in the document, and pinned by its
SHA-256 and verified by TestFormatTestVector.

go.mod specified go 1.17 but protobuf generated code (mf.pb.go) uses
go1.18+ features (any) and go1.20+ features (unsafe.StringData).
Updated to go 1.22 and ran go mod tidy.
