Adds a Manifest V3 Chrome extension that injects the detector when
DevTools opens, with a dedicated panel for browsing findings, a toolbar
popup for quick scan/toggle, and per-rule settings synced via
chrome.storage. Categorizes anti-patterns into AI slop vs quality
issues with visual differentiation (sparkle prefix, panel grouping).
Overlay labels are polished with flush positioning, cycling for
multi-finding elements, and synchronized hover darkening.
