[contrib-wave] CI: Add lint job that pins markdown link integrity (link-check)

[Gbangbolaoluwagbemiga]

Problem

README and docs occasionally rot — we have at least one stale Codecov badge pointing to a fork (Jayy4rl). We need automated link-check.

Why it matters

Documentation accuracy underwrites contributor trust.

Acceptance Criteria

• Add lychee-action step in a docs-lint.yml workflow on PRs touching **/*.md
• Allowlist intentional placeholders
• Fix the Codecov badge owner in README.md

Pointers

• README.md (Codecov badge line)
• docs/*
