Replaces Smush Pro's optimisation pipeline without the grey-wash bug. CLI commands working: wp h4b-img status wp h4b-img optimise --id=<n> wp h4b-img bulk wp h4b-img rescue Verified on dev.rds.ink: - ICC profile preservation works (the Smush-bug fix) - Bulk: 20 attachments → 487 KB saved (10.4%), 0 errors - Rescue: end-to-end mechanism verified on WorkingAsOne_horse fixture - WebP synchronous, AVIF queued via WP-Cron - Originals backed up to wp-content/h4b-img-originals/ See CHANGELOG.md for details + ../DESIGN-h4b-image-optim.md for architecture.
