1. Zellij dead session cleanup now uses exec_as_user instead of
exec_cmd — on Incus, exec_cmd runs as root which can't see
the non-root user's Zellij sessions.
2. post_cache_setup no longer calls wait_for_network — cached
images only need local file operations (git config, devbox binary),
not internet access.
3. SSH auth for `devbox code`:
- Fixed nixbld user detection in code.rs (same /home/ filter)
- Added services.openssh with PasswordAuthentication=false to
devbox-module.nix (was missing, only in standalone config)
- Forces key-based auth, preventing password prompts

Summary
Three Linux-only fixes:
Dead Zellij sessions:
zellij delete-all-sessionsnow runs viaexec_as_userinstead ofexec_cmd. On Incus,exec_cmdruns as root which can't see the non-root user's Zellij sessions — dead sessions were never cleaned up.Cached image network failure:
post_cache_setupno longer callswait_for_network(). Cached images only need local operations (copy git config, devbox binary) — the network check was unnecessary and caused failures.SSH password prompt in
devbox code:/home/filter)services.opensshwithPasswordAuthentication = falseto devbox-module.nix (was missing — only existed in standalone configuration.nix)Test plan
