refactor: unified VI, shared components, React 19, performance (#2706)

* refactor: unified VI, removed compose layer, consolidated shared components

- Unified sidebar: CollapsibleSidebar across repo/org/user/collection/compare pages
- Unified title hierarchy: H1(28px) H2(22px) H3(18px) H4(14px) across all pages
- Unified ShowSQL: all placed in title row right side
- Unified table styles: RankTable pattern (No./Name/Value) for repo/org
- Unified chart grid lines: #2a2a2c dashed splitLine on all axes
- Unified dataZoom: slim 16px slider, no data shadow
- Unified sidebar nav: left border selected state, no background highlight
- Unified spacing: section pt-8/pb-8, title pb-4, chart title mb-3
- Unified right padding: 10% on all analysis/collection layouts
- Unified OG image constants: shared lib/og-image.ts
- Unified colors: removed yellow (#f7df83) from collection pages
- Unified breadcrumb: Home icon style on collection pages with Edit link

- Removed compose layer: deleted charts/compose/org/ (17 chart wrappers)
- Removed SectionTemplate: org/user sections use ScrollspySectionWrapper
- Removed duplicate code: utils/format.ts, charts-utils/ui/, Analyze/options/
- Removed duplicate API route: /gh/repos/[owner]/[repo]
- Removed unused components: MainSideGridTemplate, SplitTemplate, SubChart, ChartLinks

- Shared chart visualizations: map-chart.ts, word-cloud.tsx, time-heatmap.tsx
- Added StickyRepoHeader for repo analysis
- Added ScrollspySectionWrapper anchors for sidebar scroll tracking
- Added RadarChart/PieChart/TreemapChart to ECharts registry
- Fixed hydration mismatch in ShareButtons
- Fixed tainted canvas export error
- Replaced native select with tabs in developer activities
- Removed Organization/Developer type labels
- Removed breadcrumbs from analysis pages
- Removed "Last active at" from org header

* refactor: UI abstractions, performance, React 19 upgrade, engineering cleanup

## Shared UI Components
- TabBar: replaces 3 inline tab implementations
- SectionHeading: replaces 25 inline heading elements
- MetricTable: replaces duplicate overview tables in repo/user pages
- LoadingSkeleton: consolidates 3 identical definitions
- useChartContainer: shared ResizeObserver hook for RepoChart/OrgChart
- createTimeSeriesOption: reduces 7 inline ECharts option builders
- PageSkeleton: shared loading.tsx skeletons

## Visual Consistency
- Removed ALL yellow accent colors (#ffe895/#f7df83/#fbe593) — primary is now white
- Unified border-radius: rounded-xl/2xl/3xl → rounded-md/sm across all components
- Unified hover colors: 31 yellow hover variants → hover:text-white
- Unified description text: 4 non-standard styles → text-[16px] text-[#7c7c7c]
- Unified dropdown/popover bg: #2f2f3a → #212122
- Unified input/select focus: yellow ring → subtle gray border
- Unified kbd styling: removed border, simplified
- Cleaned search dialog width (CSS class with !important)
- Removed card backgrounds from Repository Statistics section

## Performance
- Context values memoized (AnalyzeContext, AnalyzeChartContext, CollapsibleSidebar)
- Removed 6 remaining key={} props forcing chart remounts
- Sidebar animation: removed transition-[width] (layout thrash)
- SQLDialog lazy-loaded via dynamic import (~300 lines deferred)
- fetchCollections wrapped in React.cache for server dedup
- useTransition for tab switches and URL param changes
- TabBar onPrefetch hook for hover-based data prefetching
- staleTime 5min on RepoChart/OrgChart queries
- content-visibility: auto on ScrollspySectionWrapper
- will-change-transform on sticky elements
- requestAnimationFrame throttling on scroll handlers
- passive: true on all scroll listeners
- Font display: swap for Geist font
- Fixed layout shift: StickyRepoHeader → fixed positioning
- transition-all → specific properties (6 files)

## Next.js Best Practices
- React 18 → 19, @types/react 18 → 19
- error.tsx on all 14 routes
- loading.tsx with proper skeletons on all routes
- generateStaticParams for popular repo/org pages
- Removed contradictory force-dynamic + revalidate on trending/languages
- next/image optimization enabled (removed unoptimized: true)
- router.push → Link component (3 places)

## Engineering Quality
- Removed 9 console.log/warn from client code
- Cleaned 18 TODO/FIXME comments
- VisualizerModule type replaces 14 `any` in chart system
- Deduplicated chart color palettes
- Unified percentage formatting to number2percent
- CSS variables configured for design tokens
- Fixed duplicate splitLine properties in 7 chart files
- Removed unused @ts-expect-error directives
