fix: resolve all markdownlint errors

- Replace 68 "[here]" links with descriptive text (MD059)
- Fix table separator spacing in 6 project files (MD060)
- Add trailing newlines to 2 files (MD047)
- Disable MD060 rule for .claude/ internal files
- Update markdownlint config with MD060: false

All project files now pass markdownlint --config .github/.markdownlint.yaml
