towerops/test/test_helper.exs
Graham McInitre e6fba0c5a3 fix: register NIF compiler, add Nix shell NIF build, make NIF optional at boot
- Register :towerops_nif compiler in mix.exs so mix compile/test builds the C NIF
- Add 'make -C c_src' to nix devShell shellHook so NIF is pre-built
- Extract init_mib_resolution/0 from Application.start/2 (reduces CC)
- Wrap NIF calls in try/rescue ErlangError for graceful fallback
- Wrap test_helper.exs NIF calls in try/rescue ErlangError
- Add .nix-postgres-version to .gitignore
