[Draft] Add Fastlane release workflows for iOS and Android

[IanDBird]

Summary

• Adds a GitHub Actions workflow (release-app.yml) triggered by app/v* tags that builds and deploys both iOS and Android in parallel
• iOS: Fastlane Match for code signing, build_app for archiving, upload_to_testflight for deployment
• Android: Gradle builds a signed AAB (signing config from env vars), Fastlane Supply uploads to Google Play internal testing
• Updates existing SDK publish workflows to use sdk/v* tag prefix to avoid conflicts
• Adds shared Xcode scheme and aligns iOS bundle ID to ai.anam.lab.client
• Includes infrastructure runbook (docs/RELEASE_SETUP.md) with step-by-step setup for Apple Developer, Google Play, and GitHub Secrets

New files

File	Purpose
Gemfile + Gemfile.lock	Fastlane Ruby dependency (pinned)
fastlane/Fastfile	iOS beta and Android internal lanes
fastlane/Appfile	App identifiers for both platforms
fastlane/Matchfile	iOS certificate repo configuration
.github/workflows/release-app.yml	Combined release workflow
apps/ios/App.xcodeproj/xcshareddata/xcschemes/App.xcscheme	Shared Xcode scheme for CI
docs/RELEASE_SETUP.md	Infrastructure team runbook (11 GitHub Secrets)

Tag conventions

Tag pattern	Triggers
app/v1.0.0	App release (iOS + Android in parallel)
sdk/v1.0.0	SDK publish to Maven Central

Prerequisites before first run

See docs/RELEASE_SETUP.md for full setup. In short:

1. Configure 11 GitHub Secrets (6 iOS + 5 Android)
2. Run fastlane match appstore once from a Mac to initialize certificates
3. First Android AAB must be uploaded manually to Play Console (see bootstrap instructions in RELEASING.md)

Test plan

• Verify ./gradlew :apps:android:assembleDebug still works locally without env vars
• Verify Xcode builds locally with automatic signing after bundle ID change
• Configure GitHub Secrets and push app/v0.1.0 tag to trigger first run
• Verify AAB artifact is downloadable from workflow run
• Verify iOS build completes and uploads to TestFlight
• Push sdk/v* tag and verify only SDK workflows trigger

Summary by cubic

Adds a GitHub Actions workflow to release the iOS and Android apps via Fastlane when tagging app/v*. Switches SDK workflows to sdk/v* and adds Fastlane configs, signing setup, and docs.

• New Features

  • New release-app.yml builds iOS and Android in parallel; uploads to TestFlight and Google Play internal.
  • Validates semver from tag; build number comes from the workflow run; uploads .ipa/.aab artifacts.
  • iOS: Fastlane Match for signing; shared Xcode scheme; bundle ID set to ai.anam.lab.client.
  • Android: env-based release signing; Gradle builds signed AAB; Fastlane Supply upload.

• Migration

  • Configure required GitHub Secrets for iOS and Android (see docs/RELEASE_SETUP.md).
  • Run fastlane match appstore once on a Mac to initialize certificates.
  • Manually upload the first Android AAB in Play Console; future app/v* tags publish automatically.
  • Use sdk/v* for SDK releases; use app/v* for app releases.
