Remove redundant examples folder

Configuration examples are already provided in:
- README.md (Cursor IDE and Claude Desktop setup)
- docs/GETTING_STARTED.md (Quick setup guide)

The examples folder contained 6 OS-specific files with identical content except for path formats, which users can easily adapt from the main documentation.
