v2.0.0

QuickWin v2.0.0 — declarative FFI rewrite

This major release replaces libffi with built-in assembly call stubs and rebuilds the FFI surface as a declarative, type-checked API. Code written against the 1.x FFI API will not work unchanged on 2.x — hence the semver major.

123 files changed, +12615 / −2253 since v1.3.0.

⚠️ Breaking Changes

• libffi removed — bind() now dispatches through built-in asm call stubs; the libffi dependency and its API are gone.
• Struct syntax flattened — nested builder calls replaced by plain object literals with string sugar; layout runs on a CType IR with MSVC-compatible lowering.
• u64 / i64 unified as bigint — 64-bit integers are always bigint, on every platform.
• Token vocabulary tightened — typedef aliases and Norm dropped; the kind vocabulary is single-sourced.
• Direction-split codecs — encode / decode / alloc split by direction; struct codecs return PtrArrayBuffer (zero-initialized).
• Branded handles and NULL — handle pointer slots across structs, .d.ts and kernel32 are branded; NULL is branded per pointer type.
• Bindings regrouped under lib/windows/ — user32 / kernel32 / gdi32 / comdlg32 / shell32 / ole32 / ntdll modules, with struct definitions centralized in lib/windows/structs.ts.

Added

• Closures — JS callbacks as native function pointers, including ia32 64-bit integer returns.
• Bitfields — MSVC layout rules.
• Unions, typed pointers, NUL-terminated strings.
• Declarative bind/struct FFI — named <NAME>ptr layouts, alloc() out-params, arrayOf, tuple-typed fixed arrays.
• Codec encode / decode / alloc plus curated user32 bindings.
• Token modifiers — ! non-null and @Enum value domains.
• exec_server — GUI log window, token auth, --nogui headless mode; window enumeration and screenshot capture (clamped to screen); kills subprocess on disconnect with optional per-request timeout; win11 cmd /u keeps UTF-16 output lossless.
• TLS certificate verification for fetch / WebSocket / import(https).
• HTTP server — streaming ReadableStream response bodies, trailing headers on chunked responses, client disconnect surfaced via AbortSignal.
• fetch — recognizes the Trailer footer when completing chunked responses.
• Win11 VM — version-numbered ports and a CI matrix entry (currently disabled; enable by uncommenting).

Fixed

• DeepPartial no longer recurses into primitive brand types.
• Hardened bitfields, closure bounds checks and bindLib generics.
• 64-bit window handles written without JS bit-shift wraparound (exec_server).
• SMB: oplocks disabled in smb_wrapper to stop stale guest reads.
• Stale winpty references removed after the CreateProcess + CreatePipe exec rewrite.

Docs

• FFI notes: ! modifier cost, node:ffi gap (73–424×), callPacked attribution (90% in the JS layer).
• JSDoc @param args_N on binding parameters; binding JSDoc deduplicated.
• exec_server article and architecture notes; dev-docs overhaul.
