GitHub Action is broken:

error: attribute 'defaultPackage' in selection path 'defaultPackage.x86_64-linux' not found

• check .github in the template
• add

attribute  
'packages.x86_64-linux.default'
'defaultPackage.x86_64-linux'

• integrate nvim and rust-analyzer

Improve DevEx:

• try other nix+rust devex, see if you can get better suggestions from nvim.
• add nvim + rust-analyzer
