- Add internal/config/config.go with viper-backed Config struct - Explicit BindEnv calls for reliable env var -> config mapping (mapstructure v2 compat) - Config loads from config.json + .env, env vars take precedence - Add config.json with non-secret defaults (port, timeouts, URLs) - Fix SPA fallback: spaHandler serves index.html for unknown paths (client-side routing) - All 5 tests pass: TestHealth, TestLoadDefaults, TestLoadEnvOverride, TestLoadNetBoxURL - Add Makefile with build/dev/test/clean targets
