Filesystem server access denied for allowed paths on Windows

[robotdad]

When using a local version of the filesystem server on Windows I am getting access denied for paths that are allowed directories on Windows. I was moving to this to get off of my own fork sine a prior PR was merged but it is not in release.

To Reproduce
Steps to reproduce the behavior:

1. Setup some allowed directories on Windows
2. Try and access file with them using a local build of filesystem server

Logs
There are no errors in the logs.

Additional context
Here is an example output of read_file showing the issue.

{
  `path`: `C:\\source\\servers\\src\\fetch\\README.md`
}
Error: Access denied - path outside allowed directories: C:\source\servers\src\fetch\README.md not in c:\source, C:\Users\mgoodner

Hello, may I ask how the final solution was resolved? Please let me know. Thank you

I'm still having the same problem (Windows).

EDIT: The issue is that the path validation logic is incorrectly denying access to paths that should be allowed, because of
inconsistencies in path normalization and case sensitivity (e.g. "C:\source" is not the same as "c:\source"). I made some changes to index.ts, built with npm run build and copied the resulting index.js to AppData\Roaming\npm\node_modules@modelcontextprotocol\server-filesystem\dist\index.js
