Windows build fails due to path separator issues

[rajkumarVairam]

The build process fails on Windows due to path separator differences. The current code uses string replacement with hardcoded forward
slashes, but Windows uses backslashes.

Error:
Error: ENOENT: no such file or directory, open 'data..\data..\filename.mdx'

Solution:
Replace string manipulation with path.basename() which is cross-platform.

Environment:

• OS: Windows
• Node.js: v20.17.0
• pnpm: 10.2.0
