We actually tested this manually before opening the PR. We ran tailscaled inside the devcontainer without any /dev/net/tun device mount and it worked end to end -- tailscale status showed connected, we could ping the subnet router, SSH to an agent sandbox VM returned permission denied (correct, SSH worked but Kevin's key was needed), and curl to the fakeintake ECS service returned live data. The existing SYS_ADMIN + apparmor:unconfined capabilities in the devcontainer already grant access to /dev/net/tun without needing an explicit device mount.

P2 Badge Pin and verify the Tailscale installer

Every devcontainer prebuild now executes whatever tailscale.com/install.sh serves at that moment as root, so rebuilding this commit after an upstream installer or package change can produce a different—or broken—image, and a compromised response would gain root execution in the workspace image. Install a reviewed, version-pinned artifact and verify its signature or checksum instead of piping a mutable remote script directly to sh.

# Add bits user to the docker group. This should probably be handled by the base feature. But not working for now.
