Feature request: offline / disconnected mode

[kzorba]

I would like devenv to work in a disconnected environment (during flights for example). If we disconnect, here is an example of what we get:

# kzorba @ enigma in ~/WorkingArea/python-project on git:main x [12:43:37]
$ devenv version
devenv 1.0.1 (aarch64-darwin)

# kzorba @ enigma in ~/WorkingArea/python-project on git:main x [12:43:40]
$ devenv shell
• Building shell ...
thread 'main' panicked at devenv/src/command.rs:270:26:

Second this, also train networks can be spotty, and this would be quite annoying.
