Craft Link Checker

Added

• Initial release
• Crawls all live entries across all Craft CMS sites and verifies every link is reachable
• Two-pass crawl: entries with frontend URLs (Pass 1), then URL-less section entries (Pass 2) — both Craft 4 and Craft 5
• Extracts links from Redactor (Craft 4), CKEditor (Craft 5), Link (Craft 5), and URL fields, recursively inside Matrix and Super Table blocks
• Internal links resolved via DB lookup (no HTTP request)
• External links verified via Guzzle HEAD request (GET fallback on 405)
• Deduplication cache: each unique URL is checked only once
• Results persisted to storage/craft-link-checker/results.json
• CP utility at Utilities → Link Checker: run, monitor progress, stop, browse results, export CSV
• Settings page at Settings → Link Checker: configurable skipped hosts and path prefixes
• CLI command php craft craft-link-checker/link-checker/run for scheduled/headless runs
• Background queue job support
• Memory-efficient batch processing (50 entries at a time)
