Node.js adds ffi module, tightens fs validation

node:ffi lands as a new core module (d0fa608)

Node.js now ships a node:ffi module backed by bundled libffi, with build and CI wiring added across Makefiles and GitHub workflows. This opens the door to calling C libraries from JS in a first-class way, which is a major new capability for the runtime.

fs read APIs now validate position before returning on zero-length reads (ed05549)

fs.read(), fs.readSync(), and the promises variant now reject invalid position values even when length === 0, matching the expected argument-validation order. The added tests lock in the behavior so bad input no longer slips through on empty reads.

SQLite updated to 3.53.0 (17d03b5)

The embedded SQLite dependency was refreshed from 3.51.3 to 3.53.0, bringing in a large upstream code update. This is a significant dependency upgrade that can include behavior changes, fixes, and new SQLite features.

spawnSync now coerces string args once (54d7d14)

spawnSync was refactored to convert non-string arguments to strings a single time instead of cloning and mutating the JS array. That reduces overhead and avoids extra object churn in synchronous process spawning.

Other misc changes

• Updated gyp-next to 0.22.0 and taught it about Windows ARM64.
• Bumped nbytes to 0.1.4 with its test/build setup changes.
• Fixed macOS --shared-ffi compilation in Nix and updated the Nixpkgs pin.
