Fix Windows URL opening with query parameters (v2)

[Kamyil]

Summary

• Fixes issue T/L open bowser Not work with params #42 where browser opening didn't work with URLs containing & characters on Windows
• The previous fix (PR Fix browser opening for URLs with query parameters #44) using args() didn't work because cmd.exe still interprets & as a command separator

Root Cause

When using std::process::Command::args(), Rust quotes the arguments, but cmd /C concatenates them into a single command string where & is still treated as a command separator.

User error output showed:

'f' is not recognized as an internal or external command
'bugID' is not recognized as an internal or external command

Fix

Use raw_arg() from std::os::windows::process::CommandExt to pass the complete command string with proper quoting:

.raw_arg(format!("/C start \"\" \"{}\"", url))

This ensures the URL is wrapped in quotes that cmd.exe will respect.
