`sf org login web` timeout from Ubuntu WSL2

### Summary

`sf org login web` from Ubuntu inside WSL2 results in a socket timeout.

`sf org open` launches my browser just fine.

### Steps To Reproduce

`sf org login web` from Ubuntu in WSL2

### Expected result

It should launch the Windows browser.

### Actual result

Got `Error (SOCKET_TIMEOUT): timeout`

### Additional information

- I'm aware of https://github.com/forcedotcom/cli/issues/3368. As far as I can tell `sf org login web` should not be broken.
- Authorize Org from VSCode (remote connection to WSL) doesn't work too
- My existing authorized orgs are working. I just can't add new ones.
- I think this is important as with agentic coding trending many developers will be working in sandboxed headless environments.

### System Information

```
Ubuntu 24.04 for WSL2
@salesforce/cli/2.150.6 wsl-x64 node-v24.13.1
```

Start by reproducing `sf org login web` under Ubuntu 24.04 in WSL2 and compare its browser-launch path with `sf org open`. Trace the timeout and WSL-to-Windows browser handoff; done means web login launches the Windows browser successfully without breaking existing authorized-org behavior.
