Prose and benchmark tables use MultiforaDB; the binary, the CLI usage line, the log-message prefix and the default database file use multiforadb. Two consequences worth noting: - build.zig.zon's fingerprint is derived from the package name, so it had to change with it (Zig refuses to build otherwise). A consumer pinning this package by fingerprint needs updating. - the default --db path is now multiforadb.log, and getCmdLineOpts reports it as dbpath. An existing mongo-lite.log has to be passed explicitly with --db. The e2e harness abbreviated the old name as ML_; that is now MFDB_, including the documented ML_BIN override (MFDB_BIN) and the scratch file names. MD_ (mongod) is untouched. compare-run.sh spawned the server by absolute path under a sandbox/mongo-lite directory that no longer exists; that block already runs from tests/e2e, so it uses a relative path now. The archived reports under tests/e2e/results/ keep the old name: they record what the old binary measured.
