REA_KUNA_JOBS reached only `decompile-project`, so the export's first step,
the `kuna functions` inventory that every cold request waits for, always ran
serially. Kuna's `functions --jobs N` returns the serial inventory byte for
byte, so both inventory runs now pass the configured jobs. On a 254 MB
Mach-O the inventory takes 23 s with 8 lanes instead of 66 s; the default of
one job is unchanged.
