docs: fix markdown linting errors

- Remove duplicate 'Test Framework Structure' heading
- Fix list indentation (use 0 spaces instead of 2)
- Remove trailing spaces throughout documentation
- Fix trailing punctuation in heading (remove colon)
- Rename duplicate 'Setup Instructions' heading to 'Topology Setup Instructions'
- Ensure consistent markdown formatting across all documentation files

Resolves all MD024, MD007, MD009, and MD026 linting issues.
