GHSA-8v4j-7jgf-5rg9: Warp vulnerable to Path Traversal via Improper validation of Windows paths

The vulnerability stems from the sanitize_path function's incomplete path validation logic in Windows environments. The commit diff shows a specific addition of colon (':') validation in this function when cfg!(windows) is true. Prior to the patch, the function only checked for backslashes and '..' patterns but didn't account for colons, which are critical for Windows drive letter specification. This allowed URL paths containing segments like 'c:' to bypass directory restrictions and access arbitrary filesystem locations.
