Add src/ffi.zig + a `zig build ffi` target that emits libkuri_ffi (.dylib/.so), exporting a stateless C-ABI fetch path: kuri_fetch(url, mode) -> NUL-terminated bytes (markdown|html), kuri_free, kuri_ffi_abi_version No server, no Bridge, no shared state — reuses validator.validateUrl (SSRF guard) + http_fetch.fetchHttp + markdown.htmlToMarkdown. Pure-Zig deps + spawned curl; needs no quickjs / curl-impersonate linkage. Lets a host (e.g. Bun bun:ffi dlopen) drive kuri's fetch/render in-process instead of running the long-lived kuri server. Verified: built native (aarch64-macos, 4.9MB .dylib); Bun FFI dlopen → kuri_fetch on https://example.com → markdown rendered in-process in ~2.5s.

Adds an optional
zig build ffitarget that emits libkuri_ffi (.dylib/.so/.dll), exposing a small stateless C ABI so a host can drive kuri's fetch/render path in-process — no HTTP server, no sharedBridgestate, no subprocess.API
How it works
src/ffi.zigreuses the same helperskuri-fetchuses —validator.validateUrl(SSRF guard) →http_fetch.fetchHttp→markdown.htmlToMarkdown. Pure Zig + spawnedcurl, so the lib links no quickjs and no curl-impersonate — just libc. It cross-compiles cleanly for every target with Zig's bundled libc (verified: aarch64/x86_64-macos, x86_64/aarch64-linux, x86_64-windows).Why
Lets an embedding host (e.g. Bun
bun:ffidlopen) call kuri's fetch directly instead of running the long-lived server — handy for stateless one-shot fetches. Purely additive: one new build step + one new file; no existing target or behavior changes.Verified
zig build ffi→libkuri_ffi.dylib(native + cross targets).dlopen→kuri_fetch("https://example.com", 0)→ markdown rendered in-process.
