fix: devDependency cleanup

[stevensJourney]

Overview

PowerSync now uses @journeyapps-labs/common-sdk for interfacing with some of our micro-services. While working with this, we noticed that a few packages in micro had vitest listed under dependencies instead of devDependencies. Because of this, downstream consumers were unnecessarily pulling in those transitive packages, which added bloat to their node_modules.

This PR moves vitest to devDependencies. No runtime code has changed.

Affected packages: @journeyapps-labs/micro-codecs and @journeyapps-labs/micro-schema.

Changes

vitest → moved to devDependencies

Only used during testing — no published type definitions reference it, so there's no reason for consumers to install it.

@types/node → kept in dependencies in micro-codecs

The published .d.ts files for micro-codecs expose Buffer in their public API (e.g. Codec<Buffer<ArrayBufferLike>, ...>). Buffer is a Node.js global typed by @types/node, so consumers need it available to compile against these types.

@types/express → kept in dependencies in micro-streaming

The published .d.ts files for micro-streaming explicitly import express types (e.g. express.Request, express.Response). Moving it to devDependencies would cause TypeScript errors for consumers who don't have @types/express installed themselves.

Additional Context

@journeyapps-labs/common-sdk depends on some of these micro packages, which is how we spotted the issue:

├─┬ @powersync/cli-core link:packages/cli-core
│ ├─┬ @journeyapps-labs/common-sdk 1.0.2
│ │ └─┬ @journeyapps-labs/micro-streaming 1.0.1
│ │   └── @journeyapps-labs/micro-schema 1.0.1
