Address PR review comments for examples README

Changes based on review feedback:
1. Fix setup requirements - make sync mandatory, config optional (displays config, doesn't configure)
2. Add sync step to download backend data before running examples
3. Update expected outputs to indicate they may vary based on enabled backends
4. Fix configuration section to correctly describe precedence (local .aletheia-probe first)
5. Remove Support section as requested
6. Add reference to main configuration documentation

All review comments addressed and replied to on GitHub.
