Docs overhaul, compiler fixes, and new codegen features

New Features

• String.fromCharCode — codegen support for the static string method
• JSON.stringify for object arrays — handles arrays of typed objects via yyjson bridge
• \x and \u hex escapes — native parser now correctly handles hex/unicode escape sequences in string literals
• -g flag for native compiler — pass debug flag through to llc for debug info builds
• Strip binaries by default — output binaries are stripped unless -g is set

Bug Fixes

• .opt.bc not cleaned up — intermediate optimizer bitcode file was silently leaking after every build; fixed in both compiler.ts and native-compiler-lib.ts
• Copy-as-markdown button — rewrote to lazily load raw .md via import.meta.glob on click instead of pre-loading all pages through transformPageData; also fixed z-index stacking so the button renders above content
• Env access in native CLI — fixed process.env access when running the compiler as a native binary
• Diagnostic color propagation — color/TTY setting now propagates correctly to the native compiler's diagnostic engine
• Help command grouping — CLI help output groups commands by category

Docs

• Architecture page expanded — new sections covering LLVM IR with a live example, types and semantics (integer vs float, null safety), and why the TypeScript subset works well for LLMs
• Pipeline description corrected — was "llc (assembler) and clang (linker)"; now correctly describes the full opt → llc → clang pipeline with accurate tool descriptions
• Homepage — removed LLVM IR animation, replaced watch mode feature callout with single-binary deploy
• Installation page — clarified prerequisites
• Examples page — consolidated and refreshed
• Platform support — removed stale musl reference
• CLI reference — updated cross-compilation and flag docs

Examples

• HackerNews example updated with improved frontend (JS, HTML) and cleaner server code
• HTTP server and websocket examples cleaned up
