Usage Example doesn't work

I'm trying the usage examples, but I can't recover seeds with SSKR, every time I press enter it asks for another input, I have to end it with Ctrl+C like here:

```
C:\Users\aaa\.cargo\bin>seedtool` --out sskr -g 2-of-3 -s btwm
tantkpgowkguaeadaersrncktdjyoysalgpfuturndjyuecamhwswtwdos
tantkpgowkguaeadadsfvadtptvdrevwylwlgamnptsffguebznypriast
tantkpgowkguaeadaohkbajodkgaldlkkkaowykizmctyklalysfbglahh

C:\Users\aaa\.cargo\bin>seedtool --in sskr
tantkpgowkguaeadaersrncktdjyoysalgpfuturndjyuecamhwswtwdos
tantkpgowkguaeadadsfvadtptvdrevwylwlgamnptsffguebznypriast
^D

^C
C:\Users\aaa\.cargo\bin>

```

Start by running the documented `seedtool --in sskr` command with the two shares shown in the issue and inspect the CLI's SSKR input handling. Compare the usage example with the observed behavior; done means a 2-of-3 recovery completes after two shares without requiring Ctrl+C.
