Generated env.fish contains backslash paths (invalid in Fish) on Windows/msys

[Aalivexy]

Describe the bug

On Windows under msys2, the generated env.fish file contains backslash-separated paths (e.g., C:\Users\[username]\.vite-plus\bin) instead of forward-slash paths. Fish interprets backslashes as escape characters, causing a syntax error when sourcing the file.

The root cause lies in the crates/vite_global_cli/src/commands/env/setup.rs file. When the installation directory is under $HOME, the code normalizes the backslashes using .replace('\\', "/"). However, the alternative path (unwrap_or_else) outputs the unnormalized raw std::path::Display result, producing a path like C:\Users\[username]\.vite-plus\bin.

I can open PR if needed.
