Node compat, sqlite, and Windows fixes land

A packed day of Node-compat work: URLSearchParams errors, sqlite serialize/deserialize, fs/watch behavior, Windows pipe leaks, and more.

Node URLSearchParams now matches Node’s invalid-this and missing-arg errors (divybot9febd38) Deno’s URLSearchParams methods were updated to emit Node-compatible branding and ERR_MISSING_ARGS messages, including the right interface name and argument labels. This closes a compatibility gap in invalid-call behavior that Node tests were asserting.

DatabaseSync gains serialize() and deserialize() (littledivy3933caa) node:sqlite now supports exporting a database to a Uint8Array and restoring it back, matching Node’s newer SQLite API. That unlocks database snapshot/restore workflows and brings Deno closer to Node’s public surface.

fs.watchFile now catches more than mtime changes (lunadogbot48c2bbb) StatWatcher was broadened to compare additional stat fields, so chmod/chown, replacements that preserve mtime, and sub-resolution changes now trigger events. The bigint path is also wired through correctly, fixing missed filesystem changes in Node-compat watchers.

Windows child_process.spawn no longer leaks pipe handles (bartlomieju0377166) The Windows pipe close path now releases both the duplicated OS handle and the CRT fd slot after spawn-created pipes are torn down. This fixes a real exhaustion bug that could surface later as misleading EMFILE failures in unrelated file APIs.

SQL tagged template support is wired up for node:sqlite (divybot2366bb6) Deno filled out Node’s SQLite tagged-template API, including the SQLTagStore behavior behind db.createTagStore(capacity). This enables cached template-driven query execution with bound parameters, as in modern Node.

MessagePort listener deduplication now matches Node (littledivy261913c) parentPort.on('message') and related listener handling were adjusted so the same callback reference can’t be registered twice for the same event. That aligns worker_threads behavior with Node and avoids duplicate message delivery.

node:test top-level await no longer deadlocks (lunadogbot8cb7e56) test()/suite() now resolve in a way that doesn’t block module evaluation when awaited at top level. This fixes a common Node pattern that previously hung under Deno’s test bridge.

SocketAddress is implemented for node: net internals (littledivy0fe9e76) Deno added the internal SocketAddress plumbing that Node expects, plus the internal module exports needed to reach it. It also handles structured-clone recovery and parsing of IPv4/IPv6 host:port strings.

module.register() stops misrouting node: builtins through the loader hook (lunadogbote2feae5) When user load hooks are active, node: builtins now bypass the broken path that could fall through to the Rust loader and fail with Unsupported scheme "node". This fixes real-world tooling cases like Vite/Fresh builds that import built-ins from npm packages.
