uWebZockets v1.0.6

Added

• Added ServerConfig, named Presets (microservice, websocket_chat,
  file_server), and the fluent Server.builder API with compile-time
  with_* overrides that translate named limits into one contiguous startup
  slab.
• Added Server.builder(...).build(allocator), App.init_configured, and
  App.init_from_slab, which carve the connection pool, HTTP/1.1 request
  buffers, WebSocket message regions, response write queues, and optional
  RFC 7692 scratch from a single block.
• Added structured JSON transport rejections: oversized bodies return 413
  and oversized headers return 431 with a document naming the configured
  limit and the ServerConfig field to raise.
• Added examples/basic_microservice.zig and examples/custom_builder.zig
  with matching zig build steps.
• Added physical-core affinity and shared-nothing startup options:
  App.cluster(...).init_with_options, Server.builder(...).build_cluster, and
  ClusterOptions pin worker i to the i-th allowed physical core on Linux
  and Windows while keeping restricted cpusets and affinity-less platforms
  running unpinned.
• Added listener and connection tuning: SO_REUSEPORT on POSIX,
  TCP_DEFER_ACCEPT on listeners, and a one-shot TCP_QUICKACK request at
  accept so the hot read path stays syscall-free.
• Added a lock-free Vyukov sequence ring for cluster inboxes, removing the
  spinlock from the cross-worker wakeup path and cache-line separating the
  producer and consumer positions.
• Added examples/shared_nothing_cluster.zig plus the restructured
  docs/architecture.md, docs/memory_model.md, docs/protocols.md, and
  docs/operations.md.

Changed

• Moved per-connection HTTP/1.1 request buffers out of TcpConnection into
  the application slab; the parser now enforces a per-connection
  max_body_size policy instead of the fixed module default.
• freelist_pool can adopt caller-owned storage through from_slices and
  leaves that storage intact in deinit.
• App.init keeps its existing signature and now builds the same single slab
  through init_configured.
• Windows cluster listeners fall back to SO_REUSEADDR and thread affinity to
  SetThreadAffinityMask instead of failing when SO_REUSEPORT is missing.
• Rewrote README.md as a short onboarding document and moved deep runtime,
  memory, protocol, and operations material into docs/.
• Normalized naming to the coding convention: the JSON-RPC standard-error
  namespace is now StandardError and the internal builder type generator is
  configured_builder. The convention checker now also rejects PascalCase
  function names, snake_case type names, and camelCase fields or parameters.

Fixed

• Fixed an HTTP/2 stream-lifecycle race: an END_STREAM HEADERS frame no
  longer releases its slab slot before the server finishes processing the
  event, the server refuses to emit RST_STREAM on stream 0, and a second
  HEADERS section on a stream without a completed request is rejected as an
  unexpected trailer.
• Enforced ServerConfig.max_body_size for HTTP/2 request bodies, both
  declared and streamed, within the compiled session slab capacity.
• Fixed macOS/kqueue connection-slot and QUIC-drain leaks: canceled read and
  write callbacks that the backend can drop no longer gate slab release, and
  the close completion clears the outstanding flags.
• Fixed a shutdown hang where stopping a timer or the idle sweeper from inside
  its own tick callback re-armed it forever.
• Fixed QUIC shutdown re-entrancy: shutdown() from an HTTP/3 handler now
  defers lsquic_engine_cooldown until the active engine callback unwinds.
• Fixed WebSocket fatal-error handling: a failed parser is terminal, a close
  frame completes the frame parser instead of being re-emitted, HTTP/2 tunnels
  are reset on failure or close, and large sends split across DATA frames
  instead of committing a frame header before a rejected payload.
• Fixed an absolute-path escape in static file index appending and made static
  file traversal open every directory component without following symlinks.
• Fixed JSON-RPC perfect-hash dispatch to confirm stored method bytes after a
  fingerprint match, and widened the router's copied-path registry offset so
  filling the 64 KiB limit cannot overflow.
• Fixed slab-plan alignment so near-maximum layouts return
  error.SlabSizeOverflow instead of panicking, and rejected ServerConfig
  capacities that do not match the generated App type at compile time.
• Fixed If-None-Match precedence over If-Modified-Since, OpenAPI literal
  :/* path segments, Cluster.deinit double-call safety, the TLS plaintext
  drain continuing after close was scheduled, and the native stream adapter's
  zslay opcode names.
