support forwarding flags without --

[mesqueeb]

one of the commands I tried to run with dum:

dum test test/internal/fetch.ts -w=@magnetarjs/core

didn't work

But just npm run does work.

npm run test test/internal/fetch.ts -w=@magnetarjs/core

PS: I use npm 7.14+ workspaces

Running dum won't forward flags to npm run, it's a standalone npm run implementation which currently doesn't support the -w flag. Flags behind the script name will be forwarded to your script instead.
