Add build and release GitHub Actions pipelines

[Copilot]

• Create .github/workflows/build.yml - Build pipeline that:
  • Installs Node.js dependencies
  • Downloads frpc binaries from fatedier/frp releases
  • Builds the frontend with npm
  • Builds Android APK using Gradle
• Create .github/workflows/release.yml - Release pipeline that:
  • Triggers on tag push or release creation
  • Runs the full build
  • Uploads APK artifacts to the GitHub release
• Validate workflow syntax with YAML parser
• Run code review
• Run CodeQL security scan - Fixed missing permissions block
• Fix actions/download-artifact vulnerability - upgraded to v4.1.8
• Change workflow to track master branch instead of main
• Fix build error - removed unused carbon-preprocess-svelte import from svelte.config.js
• Fix build error - changed fallback from app.html to index.html and removed unnecessary copy plugin from vite.config.ts
• Fix gradlew permission denied error by adding chmod +x before running gradlew
• Upgrade JDK from 17 to 21 to match Capacitor requirements

Original prompt

I need to add build pipeline and release pipeline for the project. Read the readme and download the necessary dependency when build

@copilot You need to track branch master

@copilot You need to track branch master

Updated the build workflow to track master branch instead of main in commit e0c8e3b.

Fixed in commit d990787. The build was failing because svelte.config.js imported carbon-preprocess-svelte which wasn't listed in package.json. Since the import (optimizeImports) was never used, I removed it.

@copilot Error: ENOENT: no such file or directory, copyfile 'build/app.html' -> 'build/index.html'

@copilot Error: ENOENT: no such file or directory, copyfile 'build/app.html' -> 'build/index.html'

Fixed in commit 888794e. The build error occurred because the custom Vite plugin tried to copy build/app.html before the SvelteKit adapter had generated it. I changed the adapter's fallback option from 'app.html' to 'index.html' (which is what Capacitor expects) and removed the unnecessary copy plugin from vite.config.ts.

Fixed in commit 54d2e10. Added chmod +x ./gradlew before running the assembleRelease command to grant execute permission to the gradlew script.

FAILURE: Build failed with an exception....

Fixed in commit 181b788. The Capacitor Android project requires Java 21 (as specified in capacitor.build.gradle), so I upgraded the JDK version in the workflow from 17 to 21.
