Fix documentation issues in prompt-caching examples

- Update package.json scripts to use correct anthropic- prefixed filenames
- Fix file path references in comments and README
- Fix model name consistency (claude-3.5-sonnet → claude-3-5-sonnet)
- Update README to reference directory instead of single file
