Pixellize Site Issue Scanner

0.4

New SEO checks:
* Canonical Tag Audit detects missing, conflicting, or mismatched canonical link tags. One-click Edit Canonical popup writes to Yoast, Rank Math, AIOSEO, and SEO Framework.
* Open Graph and Twitter card audit. Flags missing og:title, og:image, twitter:card, twitter:image, and og:image dimensions below the recommended 1200×630.

New crawl reliability and reporting:
* Resume After Crash. Crawl state is saved to the database every few pages, so a closed tab or page reload shows a Resume banner instead of losing progress.
* Diff Between Scans. Each report shows how many issues are new and how many were fixed since the previous scan.
* Live elapsed-time timer in the crawl progress area.
* Crawl duration shown on Dashboard Recent Reports.
* Bulk select with Delete Selected on Settings page Report Management.
* Top-of-page review prompt linking to wordpress.org reviews. Dismissible per user.

Faster crawl:
* URL list cached 5 minutes so repeat scans start instantly.
* Sitemap presence detection moved to a non-blocking background call. HEAD checks replace full GET so the first scan no longer waits on slow responses.
* Issues are buffered per page and written with a single multi-row INSERT.
* Asset and link timeouts shortened to 8-10 seconds so slow targets fail fast.
* Well-known reliable CDNs (Google Fonts, jsDelivr, cdnjs, jQuery CDN, Bootstrap CDN, Font Awesome, Gravatar, etc.) skipped from broken-status checks.

UI:
* Drill-down report header shows the current issue title and subtitle with a back button on the right.
* Recent Reports rendered as a clean table on the Dashboard.
* How-to-Fix guide moved above the report wrap.
* Find and Replace modal header changed from purple gradient to solid black.
* Start Full Scan and Stop buttons toggle visibility (no more greyed-out states).
* Crawl status text hidden in favor of timer and page-count indicators.

Fixes and removals:
* Pages with a noindex tag are no longer flagged for missing canonical.
* Crawl Mode setting removed (plugin always runs Full Crawl).
* Delete All Data Forever Danger Zone removed (bulk select replaces it).
* Export CSV button and Duration column removed from Settings Report Management table.
