run_sorter() fails after pip 26.0+ due to deprecated #egg= syntax

[esutlie]

Hey! Running into an issue with containerized sorting using installation_mode="github" (or "auto"). Modern pip (26.0+) rejects the #egg= fragment syntax when extras are included.

The error:

× The 'spikeinterface[full]' egg fragment is invalid
hint: Try using the Direct URL requirement syntax: 'name[extra] @ URL'

The current code in install_package_in_container() builds:

pip install ... https://github.com/.../archive/main.tar.gz#egg=spikeinterface[full]

But pip 26.0+ wants the Direct URL syntax instead:

pip install ... "spikeinterface[full] @ https://github.com/.../archive/main.tar.gz"

This was a bit tricky to track down since the pip failure is silent. It only shows up later as a ModuleNotFoundError when the container tries to import spikeinterface.

Thanks for finding that out! Would you have time to make a small PR to fix it?

Anything we can add to make failures like this less silent? Or is that down to pip?
