V1.5.0

Bug Fixes
- SVG gradient ID collision - Each overlay now gets a unique vs-icon-grad-{n} ID via overlayIdCounter, so multiple video overlays render their icons correctly
- Slider max mismatch - Overlay strength slider max changed 10 → 7, blur max 5 → 2, step 0.01 → 0.05 to match popup values exactly
- processedVideoCount desync - Removed the manual counter entirely, getStatus now returns trackedVideos.size
- Dead Code Removed
- SVG filter creation - Extracted createUnsharpFilterElement() and createFilterSVG() helpers, eliminating ~120 lines of duplicated SVG construction
- Settings apply logic - Extracted applyOrRemoveSharpening() and handleSettingsChange(), used by both storage.onChanged and runtime.onMessage listeners
- findVideosInCustomElements - Uses Set for O(1) dedup instead of Array.includes
scanForVideos - Also uses Set for merging custom element videos
- Reddit scanning - Reduced from 5 sequential scans (0/500/1000/2000/3500ms) to 3 (0/800/2000ms), with better debouncing (300ms instead of 200ms)
Memory leak fix - scanForVideos now cleans up disconnected videos from trackedVideos on each scan
- Popup and overlay upgraded from generic system font stack to Segoe UI Variable / SF Pro with fallbacks
- Monospace values use Cascadia Code / Fira Code / JetBrains Mono
- Slightly refined color palette (deeper backgrounds, softer accents)
