I inspect the devtools through chrome://inspect/#pages image

Research direction
Investigate the remote debugger path conversion in Node.js. The issue reports that Chrome DevTools incorrectly uses the local OS (Host.isWin()) instead of the remote Node.js OS when setting breakpoints, causing breakpoints to fail on Linux when debugging from Windows. Look at the inspector protocol and Node.js's debugger module (e.g., `lib/internal/inspector agent.js`) to understand how paths are converted. Determine if Node.js can provide the remote OS type to the devtools frontend or if the path conversion should be handled differently.
