`util.inspect()` ignores `breakLength: Infinity` when `depth: Infinity` is also set in some cases

### Version v25.1.0 ### Platform ```text - Windows: Microsoft Windows NT 10.0.26200.0 x64 - macOS: Darwin MacBook-Pro.local 24.6.0 Darwin Kernel Version 24.6.0: Mon Jul 14 11:30:51 PDT 2025; root:xnu-11417.140.69~1/RELEASE_ARM64_T8112 arm64 - Linux: Linux myhost 6.8.0-45-generic #45-Ubuntu SMP PREEMPT_DYNAMIC x86_64 GNU/Linux ``` ### Subsystem util ### What steps will reproduce the bug? When `util.inspect()` is called with both `breakLength: Infinity` and `depth: Infinity`, the output unexpectedly contains line breaks in Node.js v25.x. In contrast: - Using only `breakLength: Infinity` (with default `depth`) works correctly and produces a single-line output. - The issue appears only when `depth` is explicitly set to `Infinity`. This behavior did not occur in Node.js v24.x, so it appears to be a regression. A minimal reproducible example is provided below. ```bash $ nvm use 24 Now using node v24.11.0 (npm v11.6.1) $ node Welcome to Node.js v24.11.0.
