[Windows] Opening with deep link duplicates projects

[Rettend]

Description

This PR added the deep link for the desktop app: #10072
where I fixed this specific case but that change ended up being removed before the merge.

I think it would be better to fix Windows path issues once and for all.

Plugins

No response

OpenCode version

v1.1.48

Steps to reproduce

Opening a project with ctrl+o and the deep link opens the project twice, I see this in the sidebar:

• C:/Users/user/Documents/GitHub/repo
• ~\Documents\GitHub\repo

This is both a project path bug and a display bug with the sidebar.
