Remove zeebo dependency

[MarcosDY]

The zeebo/errs dependency is no longer serving its intended purpose in the plugins, as our use case has evolved. A new version, zeebo/errs v2, is available, aligning with updated error-handling standards. However, given that:

• We no longer rely on classes (now referred to as tags),
• There's no longer a need to attach metadata to errors,

we should evaluate whether to upgrade to zeebo/errs v2 or remove the dependency entirely. My recommendation is to remove the dependency if there’s no clear benefit in adopting the new version.

I think we're in agreement that we can just remove this dependency.

Are we seeking to preserve or remove the stack trace output that Zeebo adds silently as part of its error handling?
