📝 Walkthrough

Walkthrough

A GitHub Actions workflow configuration for link checking was updated to remove exclusions, reinitialize error variables, improve error counting logic with fallback handling, and ensure broken link counts are always written to output.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow .github/workflows/link-checker.yml	Removed exclusions (tornadocash.eth.link, localhost, 127.0.0.1) and README.md from link check targets. Initialized BROKEN variable to 0, updated error counting with improved grep fallback logic, and added guard to ensure broken_count is always written to GitHub output even when out.md is missing.
