fix(node): require compatible Node.js types (#3829)

## Summary

- require Node.js 18-compatible type declarations when TypeScript
consumers install them
- keep the type peer optional for JavaScript-only consumers
- add a regression test tying the Node type peer range to the supported
runtime

## Root cause

LanceDB requires Node.js 18 or newer, and its public types expose Apache
Arrow declarations that import built-ins through the node: scheme. The
package did not declare a matching @types/node peer requirement, so npm
accepted projects pinned to Node 12 declarations and TypeScript then
reported that node:stream and node:fs/promises did not exist.

## Validation

- pnpm lint
- pnpm build
- pnpm run docs
- pnpm test --runInBand (678 passed, 5 skipped)
- packed-package consumer probe rejects @types/node 12.20.55 and
installs with @types/node 18.19.130

Fixes #1713
