@MayNiklas

Fix the Claude Code VS Code extension on NixOS when using Remote SSH. The bundled claude binary doesn't work on NixOS due to hardcoded library paths. This Home Manager module runs a systemd user service that watches for extension installations and replaces the binary with a symlink to the NixOS claude-code package.
