Purpose

Makes this repository the home of the SDK quickstarts (thunder-id/thunderid#5904). Each quickstart moves here from its SDK repository, keeps its README and setup instructions, and now runs on its own against the published SDK release.

Sample	Depends on
quickstarts/ios	ios-sdks from 1.4.0 (SwiftPM and the Xcode project)
quickstarts/android	com.github.thunder-id:android-sdks:v1.4.0 (JitPack)
quickstarts/flutter	thunderid_flutter: ^1.2.0
quickstarts/react	@thunderid/react 1.4.0, @thunderid/react-router 1.3.0
quickstarts/vue	@thunderid/vue 1.4.0
quickstarts/nextjs, quickstarts/nuxt, quickstarts/browser, quickstarts/express, quickstarts/node	the matching @thunderid/* 1.3.0

Approach

• Layout: the quickstarts sit under quickstarts/<platform>, so they are released as sample/quickstarts/<platform>/v*.
• Samples: copied from each SDK repository's tracked files only. Local workspace links (workspace:*, path: ../.., includeBuild, XCLocalSwiftPackageReference) are replaced with the published releases. Every app version starts at 0.0.0, like the existing samples did before their first release.
• JS quickstarts: each now has its own pnpm-lock.yaml, .gitignore, and pnpm-workspace.yaml (allowBuilds). nextjs carries over the postcss override and nuxt the node-forge/braces audit ignores from javascript-sdks, each with its justification. prepare-dev.cjs no longer rewrites workspace:* deps, since there are none. StackBlitz badges now point here.
• PR builder: discovery finds a sample's stack by the manifest at its root (package.json, pubspec.yaml, settings.gradle.kts, Package.swift). New Flutter (analyze + debug APK), Android (assembleDebug) and iOS (swift build on macOS) jobs join the Node.js one. The Node.js job now runs format:check/lint/build only where a sample defines them, because the server quickstarts have no build step. This also brings integrations/flutter-app-auth under CI.
• Release: the per-sample jobs become one matrix job planned from the checked sample_* inputs (14 inputs in total). Commit, tag, pack and release steps are unchanged. bump-version now also bumps versionName/versionCode in build.gradle.kts and MARKETING_VERSION/CURRENT_PROJECT_VERSION in project.pbxproj. The iOS Info.plist reads both from the project.
• README: lists the quickstarts.

Verified locally: every JS quickstart installs, passes pnpm audit --audit-level=high, and builds or loads against the published packages. quickstarts/android runs assembleDebug against JitPack v1.4.0. quickstarts/flutter passes flutter analyze and flutter build apk --debug against 1.2.0. quickstarts/ios builds with xcodebuild (simulator) and swift build against 1.4.0. The new bump logic was tested on Gradle and pbxproj fixtures, and the release plan step on sample inputs. The workflows themselves have not run on GitHub yet.
