📝 Walkthrough

Walkthrough

The repository migrates package builds from tsup to tsdown. It updates shared build helpers, package scripts, root configuration links, Solid integrations, ignore rules, and development dependencies.

Changes

tsdown migration

Layer / File(s)	Summary
Shared build contracts `.github/renovate.json`, `.gitignore`, `eslint.config.js`, `package.json`, `scripts/getTsdownConfig.js`, `packages/eslint-plugin-query/...`, `packages/preact-query-devtools/...`	Repository tooling and shared build configurations now use tsdown options, types, and output handling.
Package build wiring `packages/angular-query-persist-client/...`, `packages/preact-query-/...`, `packages/query-/...`, `packages/react-query-*/...`, `packages/vue-query/...`	Package scripts invoke tsdown. Package configurations and root links reference the tsdown shared configuration.
Specialized build configurations `packages/query-devtools/...`, `packages/solid-query-devtools/...`, `packages/solid-query-persist-client/...`, `packages/solid-query/...`	New tsdown configurations define production, development, JSX, declaration, environment, minification, browser resolution, and Solid plugin settings.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 8a4dc

The PR replaces tsup configuration with tsdown across packages; no actionable merge-blocking risk remains beyond normal checks.
