feat: add global search, mobile drawer navigation, and View Transitions fixes

[dongjiang1989]

Summary

• Global Search: Add Ctrl+K / ⌘K search modal powered by Fuse.js with lazy-loaded build-time index (/search-index.json), fuzzy matching across blog posts, projects, adopters, events, and static
  pages, bilingual support (zh/en), keyboard navigation, match highlighting, and View Transitions compatibility
• Mobile Drawer Navigation: Replace hamburger-expanded nav with a slide-in drawer panel featuring tree-structured 2-level navigation, theme/language toggles in drawer footer, backdrop overlay,
  ESC/backdrop/link-click dismiss, and auto-close on desktop resize
• Adopter Modal Reliability: Move adopter modal to Layout-level component to fix View Transitions breakage; add retry mechanism and data reload on every open/swap for multi-cycle reliability
• Landscape Mobile Fix: Replace CSS-only transform: scale() with JS dynamic wrapper height to eliminate excess scroll space on mobile
• Project Detail Icons: Render project icon images on detail pages with first-letter gradient fallback

Changes

Added

• SearchModal.astro — global search with Fuse.js, lazy-loaded index, grouped results, <mark> highlighting, ↑↓/Enter/Esc
• SearchButton.astro — header search trigger button
• search-index.json.ts — build-time endpoint aggregating 5 content sources (posts, projects, adopters, events, pages)
• AdopterModal.astro — Layout-level adopter detail modal with hash routing and retry mechanism
• events.ts — shared event data source for events page and search index
• Mobile drawer (#mobile-drawer) with tree-structured nav, connector dots, backdrop blur
• Project detail page icon rendering (data.icon → <img>, fallback → gradient circle)

Changed

• Header.astro — mobile drawer with tree nav; ToggleTheme/ToggleLanguage wrapped in hidden md:flex
• Layout.astro — include AdopterModal at Layout level
• BasicScripts.astro — remove conflicting mobile menu handlers (h-screen/bg-page/overflow-hidden)
• adopters.astro — remove inline modal HTML/JS (moved to AdopterModal.astro)
• landscape.astro — JS scaleLandscape() with dynamic wrapper height on resize/swap
• navigation.ts — add href to "博客" nav link
• .cache/ — refresh project stats (⭐18,727) and contributors (170 from 60 repos)

Fixed

• Search modal DOM refs stale after View Transitions page swap → refreshRefs() + attachElementListeners()
• Adopter modal broken after navigation/multi-cycle → loadAdopterData() on every open + astro:after-swap
• Adopter direct URL hash not showing card → retry mechanism (20 × 50ms)
• Same-page hash navigation from search results → preventDefault() + manual window.location.hash
• aria-hidden focus warning → blur() before hiding modal
• Window resize losing search box → removed offending hidden class toggle in BasicScripts
• Desktop theme/language toggles visible on mobile → hidden md:flex wrapper divs
• "博客" nav link not navigating → added href: getBlogPermalink()
• Astro hints → added is:inline to AdopterModal JSON script, removed deprecated position="right"
