This bumps the pinned Node.js version in .nvmrc and the test matrix from 22.12 / 22.12.x to 22.23.4, the October 2026 Node.js security release for the 22.x line. The test matrix entry previously tracked the engines minimum (22.12), so CI now tests on 22.23.4 instead while engines is unchanged.

CI note: Test (41, 22.23.4, ubuntu-latest) (and Test (45, 22.23.4, ubuntu-latest) in the same run) failed in the Electron spec runner, not because of this PR. The failing assertions (should load the extension in newly created sessions after a "Failed to start Devtron service-worker ... trying again" retry, and the ipcRenderer.sendSync / ipcMain.handleOnce tracking tests) are the same intermittent failures seen with the old 22.12.x pin on unrelated PRs (e.g. runs 37498976034 and 39675277357). These specs run inside Electron's bundled Node, so the setup-node version doesn't affect them. Re-running the failed jobs once.
