fix: use ReportConfig.max_examples instead of hardcoded limits (#114)

[fazalpsinfo-cmyk]

Fix: ReportConfig.max_examples ignored

Three report generators hardcoded their sample/error limits instead of reading ReportConfig.max_examples:

File	Before	After
terminal.py	results[:5]	results[:config.report.max_examples]
markdown.py (errors)	errors[:10]	errors[:config.report.max_examples]
markdown.py (samples)	min(len(results), 10)	min(len(results), config.report.max_examples)

html.py and json_report.py already iterated over all results without a limit, so they were left unchanged.

Fixes #114
