Fix chat completion return error for stream clients

[PylotLight]

Updated StreamReader Close() returns with error type and and connected dependencies.
Tested building and running of the cli which seems to work on my machine.

Note: these changes were required to get the cli to work on my machine, not sure if there's a better solution but it works for me and thought I'd get someone to look over it.

This PR is intended to address this issue: #269

• this has too many changes, one of which introduces a bug fixed in feat(deps): update bubbletea, bubbles, lipgloss #271
• tests would not compile, I suspect

reopened as #272

thanks for the nudge though 🙏

That makes total sense. closing this one seeing you have your own official fixes on the way, cheers.
I'll try keep changes narrower in future.
