v0.5.46

• A positioned write costs its own bytes. fs.writeSync at a position that is
  not the file's end copied the whole file and wrote it all back; the binding
  now calls the tree's writeAtSync, which VirtualFS answers in place in a
  buffer the file owns and nobody holds (a copy or a read's result is never
  changed by a later write). Postgres in a tab, whose commits rewrite a page of
  its 16 MB write-ahead log, went from 44 ms a commit to under 1 ms with
  browser-substrate's store answering writeAtSync too.
• require.resolve(id, { paths }) honours paths as Node does: each entry,
  relative ones against the working directory, is where the lookup starts; a
  non-array or a non-string entry is refused with Node's codes. A World's
  injector found a Prisma adapter the application installs this way.
