I've taken a look at the changes and see that this PR adds a post-deployment step to enforce 600 permissions on the remote .env file, which should prevent insecure default permissions from exposing secrets.

Hey @dumko2001 — securing .env permissions to 600 is a solid improvement. Would you be able to rebase onto the latest main? The repo has been moving quickly and we want to evaluate this against the current state of things. Thanks!

@cv hey successfully rebased.check it out when you have time

@drobison00 thanks

Not a duplicate of #186 (merged). #186 adds `chmod 600 .env` inside the sandbox during startup. This PR adds it on the remote host after SCP during `deploy()`. Different locations protecting different files.

The deploy function has been restructured in #691 (SSH TOFU) — you'll need to rebase. The fix itself is a valid one-liner that #691 doesn't include.

@cv have rebased, pls take a look
