Add automated link validation workflow with configurable scope

[Copilot]

Implements automated link checking across the repository with issue creation for broken links.

Implementation

Workflow (.github/workflows/check-links.yml)

• Scheduled weekly runs (Mondays 9 AM UTC)
• Manual trigger with scope selection: external (default), internal, or all
• Scans Markdown, HTML, JSON, and Python files
• Auto-creates/updates issues with link-check label when links break
• Duplicate issue detection to avoid noise

Link Checker

• Uses lycheeverse/lychee-action@v2 (Rust-based, async)
• Dynamic lychee.toml generation based on scope
• 3 retries with 2s backoff, 20s timeout, 8 concurrent requests
• Excludes Python build artifacts and version control directories

Scope Behavior

• external: Excludes links to this repository via exclude_path regex
• internal/all: Checks all links (no filtering applied)

Issue Format

## 🔗 Broken Links Detected

**Check Scope:** external links
**Workflow Run:** [link]
**Date:** 2026-02-01 19:21:23 UTC

### How to Fix

Documentation

• Added workflow badge and CI/CD section entry in README
• Documented scope options and manual trigger usage

Original prompt

Create a workflow that will look through the entire repository for links to other things that are not our own repository actually include all links, scratch only outside links, although I guess make it a possibility that you could either select outside links or internal links, anyways the purpose of the workflow is to check these links and whether they are still valid, if they are no longer valid, they need to be turned into an issue and let us know that it's not valid
