feat: pre-built iOS XCUITest bundle for zero-config install

[docer1990]

Summary

• Add pre-built iOS XCUITest bundle support for zero-config installation
  on Apple Silicon Macs — no Xcode IDE or source checkout required
• Extend release workflow with a macOS CI job that builds the iOS test
  bundle, archives it as ios-automation-server.tar.gz, and includes it in
  GitHub Releases
• Update install.sh to download and extract the iOS bundle on macOS
  arm64 (skipped on Linux and Intel Macs with informational messages)
• Add dual-path discovery in ios_start_automation_server: prefers
  pre-built bundle via xcodebuild test-without-building, falls back to
  source build automatically if the bundle fails
• Extract resolveInstallDir() helper shared by APK and xctestrun
  discovery
• Extract startAndPollServer() helper to eliminate duplicated polling
  logic between primary and fallback paths

Test plan

• ./gradlew :app:test passes (includes new ToolFactoryPathTest
  cases for findXctestrun and buildXcodebuildCommand)
• Run install.sh on macOS arm64 and confirm the iOS bundle is
  extracted to ~/.local/share/visiontest/ios-automation-server/
• Start ios_start_automation_server with a pre-built bundle
  installed and verify it uses test-without-building
• Delete the pre-built bundle and verify it falls back to source
  build from the Xcode project

Pull request overview

Adds a zero-config installation path for iOS automation on Apple Silicon by shipping a pre-built XCUITest bundle in releases, extending the installer to fetch it, and teaching the MCP server to prefer xcodebuild test-without-building with an automatic fallback to source builds.

Changes:

• Add ios-release-build CI job to build/archive an iOS XCUITest bundle and attach it to GitHub Releases.
• Update install.sh to download/extract the iOS bundle on macOS arm64 (skip elsewhere with informational output).
• Update ios_start_automation_server to prefer pre-built .xctestrun discovery, with source-build fallback; refactor shared helpers and add unit tests.
