JetBrains (Rider): project paths containing spaces are URI-encoded (%20) when creating the project .continue directory on Windows

Summary

When using Continue in JetBrains Rider on Windows, creating or editing the project-specific Continue configuration causes the plugin to create a .continue directory under a URI-encoded filesystem path.
Instead of using the actual project path containing spaces, Continue creates directories where spaces are replaced with %20, resulting in an incorrect location outside the real project directory.

Environment

OS: Windows 11
IDE: JetBrains Rider 2026.2.0.2
Continue: 1.0.67
Project type: Unity/Rider project

Steps to reproduce

• Create or open a project located at: C:\Unity Projects\My Project
• Open the project in JetBrains Rider.
• Use Continue to create or modify the project-specific Continue configuration.
• Check where the .continue directory is created.

Expected behavior

The project configuration should be created inside the actual project directory:

C:\Unity Projects\My Project\.continue

Actual behavior

Continue creates the directory under a URI-encoded path instead:

C:\Unity%20Projects\My%20Project\.continue

As a result, the configuration is written to an incorrect location.

Start by tracing the JetBrains project-path handling used when creating the project-specific .continue directory, searching for where filesystem paths are converted to URIs. Reproduce on Windows with a project path containing spaces, then verify that the directory is created at the actual path and not the %20-encoded location.
