[Feature]: Piping stdin to AI should still let you provide a prompt separately

[alexboutros]

Current Behavior

If I do something like "ls | wsh ai - "how many files are here"", it only pipes the output of ls to the AI block, and does not include the question I asked. This seemed to work on on macos.

Expected Behavior

ls | wsh ai - "how many files are here" should pipe the ls output to the AI block and the AI block should read from stdin with -.

Steps To Reproduce

1. Run waveterm
2. run ls | wsh ai - "how many files are here"
3. Observe that AI block doesn't read the stdin text
