[BUG] Hot reloading fails to create hotwatch

[brooksmtownsend]

Describe the bug

When attempting to hotwatch a file on disk, I get this message:

This likely has to do with changing return values and the hotwatch module.

To Reproduce

Steps to reproduce the behavior:

1. Try to hotwatch a signed actor file
2. See error

Expected behavior

Hotwatch begins and changes to the signed actor refresh it

Environment (please complete the following information)

• OS: [e.g. Linux, MacOS, Windows] MacOs
• Arch: [e.g. x86_64, aarch64] aarch64
• wasmCloud Version: [e.g. 0.51.0] 0.58.2

@vados-cosmonic didn't you fix hotwatching? I believe we can close this issue

[vados-cosmonic]

I personally haven't had issues with hot-reloading local files -- I don't remember working on hot-watching specifically though? I only worked on size upload limits IIRC...

I vaguely remember something with inotify (possibly having to install it locally) but I don't think I made a change related to that in wasmcloud-otp...
