Walkthrough

The PR migrates Bruno App Storybook to Rsbuild, updates build configuration, tolerates remote image failures, adjusts Electron Git utilities, and changes Playwright readiness checks to use build-ready stdout output.

Changes

Application build and Storybook

Layer / File(s)	Summary
Storybook Rsbuild migration package.json, packages/bruno-app/package.json, packages/bruno-app/storybook/main.js	Storybook webpack packages and loaders are removed. Rsbuild Storybook packages are added. The Storybook framework now uses storybook-react-rsbuild.
Rsbuild runtime and image handling packages/bruno-app/rsbuild.config.mjs, packages/bruno-app/plugins/remote-images/loader.cjs	The worker threads external is renamed to node:worker_threads. Failed remote image downloads now log warnings and skip the affected URLs.

Electron Git utilities

Layer / File(s)	Summary
Git utility instance and declarations packages/bruno-electron/package.json, packages/bruno-electron/src/utils/git.js	simple-git is set to version 3.32.3. Git utilities reuse the path-specific instance and use const for non-reassigned variables.

Playwright server readiness

Layer / File(s)	Summary
Build-ready server detection playwright.benchmark.config.ts, playwright.config.ts	Playwright now waits for the ready built in stdout message instead of polling http://localhost:3000.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 2fce3

The Storybook build migration is generally mergeable, but the benchmark configuration may start duplicate development servers because two wait-only entries cannot reuse an existing server as configured. This creates a bounded CI or benchmark reliability risk that should have explicit owner awareness or follow-up.

Poem

Rsbuild lights the Storybook stage
Images skip a broken page
Git holds its roots with care
Playwright hears “ready” in the air
Build tools march in tidy pairs

Pull request overview

This PR migrates the Bruno app’s Storybook setup away from the Webpack 5 builder to an Rsbuild-based Storybook framework, with supporting dependency and build-config updates aimed at reducing the Webpack-related dependency surface (and associated CVEs).

Changes:

• Switches Storybook configuration in packages/bruno-app from @storybook/react-webpack5 to storybook-react-rsbuild, and updates Storybook dependencies accordingly.
• Updates Rsbuild configuration (including an immutable alias and an externals tweak) and makes the remote-images loader more failure-tolerant.
• Includes small supporting updates to Playwright webServer config and a minor git.js refactor/caching tweak in bruno-electron.
