Add [[nodiscard]] to VkShaderModule::loadFromFile, Shader::loadFromFile/ loadFromSource, AssetManifest::load, DbcLoader::load — all return bool indicating success/failure that callers should check. Suppress with (void) at 17 call sites where validity is checked via isValid() after loading rather than the return value (m2_renderer recreatePipelines, swim_effects recreatePipelines).
