Baixar Bun 1.3.13 per a Windows

Fixes 82 issues (addressing 381 👍). bun test --parallel, --isolate, --shard, and --changed, bun install streams tarballs to disk using 17x less memory, source maps use 8x less memory, 5.5x faster gzip with zlib-ng, Range request support in Bun.serve(), SHA3 in node:crypto and WebCrypto, ws+unix:// WebSocket client, and many bugfixes and Node.js compatibility improvements

Features
- bun test --isolate runs each test file in a fresh global environment within the same process, draining microtasks, closing sockets, cancelling timers, killing subprocesses, and creating a clean global object between files.
- bun test --parallel[=N] distributes test files across up to N worker processes (default CPU count), partitioning for cache locality and stealing work from idle workers; output remains identical to serial execution.
- bun test --shard=M/N splits test files across CI jobs, sorting by path and distributing round‑robin; works with --changed and --randomize, exits gracefully when a shard has no files.
- bun test --changed runs only test files affected by git changes, building an import graph and filtering to transitive dependents; supports --watch for re‑filtering on every restart.
- bun install streams tarballs to disk: extracts package tarballs while downloading, using only in‑flight HTTP chunks plus fixed buffers, reducing memory usage by ~17x.
- Faster bun install with isolated linker: `bun install --linker=isolated` speeds up installs in peer‑heavy monorepos.
- Source maps use up to 8x less memory: compact bit‑packed binary format (~2.4 B per mapping) replaces full VLQ list, reducing resident size from ~11 MB to ~1.3 MB for large projects.
- Bun’s runtime uses 5% less memory: upgraded mimalloc to v3 and added libpas scavenger support for Windows and Linux, improving baseline usage and reducing hangs/crashes.
- Upgraded JavaScriptCore engine (1,316 upstream commits) with performance improvements such as inline cache for array length, property keys, string length folding, toUpperCase intrinsic, fast path for String#indexOf, redundant mov removal, cached date formatters, wider bulk copy in GC‑safe memcpy, SIMD‑accelerated case‑insensitive comparisons, and SIMD fast path for identifier parsing.
- Faster addEventListener, dispatchEvent, and DOM events via ~270 upstream WebKit commits.
- File streaming improvements in Bun.serve(): Response(Bun.file(path)) now streams incrementally on SSL and Windows, reducing memory usage for large files.
- Range request support in Bun.serve(): automatic handling of `Range` headers for static and dynamic file responses, returning 206 Partial Content or 416 as appropriate.
- Up to 5.5x faster gzip compression with zlib‑ng 2.3.3: SIMD‑accelerated CRC32, Adler32, longest‑match and chunk‑copy operations; benchmarks show 2.5‑5.5× speedups for gzip/deflate.
- Faster array iteration in Bun’s internals: up to 1.43× speedup for common cases by reading elements directly from JSC’s butterfly memory.
- SHA3 support in WebCrypto and node:crypto: SHA3‑224/256/384/512 available via `crypto.createHash`, `crypto.createHmac`, `crypto.subtle.digest`, etc.
- X25519 deriveBits support in SubtleCrypto: full X25519 key agreement implementation, handling small‑order public keys per RFC 7748.
- WebSocket client now supports `ws+unix://` and `wss+unix://` URLs for Unix domain socket connections, with proper Host header and proxy handling.
- Standalone HTML built with `bun build --compile --target browser` now inlines file‑loader assets imported from JavaScript as data URIs.
- `bunx claude` is now an alias for `bunx @anthropic-ai/claude-code`.
