* ✨ Improve error handling and exception formatting
- Enhance exception formatting with visual separators and cause chaining
- Add new handler for :internal error type
- Refine error types: change assertion-related errors to :assertion type
- Improve error messages and hints consistency
- Clean up error handling in zip utilities and HTTP modules
* 🐛 Properly handle AbortError on fetch request unsubscription
When a fetch request in-flight is cancelled due to RxJS unsubscription
(e.g. navigating away from the workspace while thumbnail loads are
pending), the AbortController.abort() call triggers a catch handler
that previously relied solely on a @unsubscribed? flag to suppress the
error.
This was unreliable: nested observables spawned inside rx/mapcat (such
as datauri->blob-uri conversions within get-file-object-thumbnails)
could abort independently, with their own AbortController instances,
meaning the outer unsubscribed? flag was never set and the AbortError
propagated as an unhandled exception.
Add an explicit AbortError name check as a disjunctive condition so
that abort errors originating from any observable in the chain are
suppressed at the source, regardless of subscription state.
