Updated extract-release-notes.sh to follow new format:
**Environment:** {ENV}
**Tag:** {TAG}
## What is new in this release
{changelog content}
Improvements:
- Moved environment and tag info to the top
- Added 'What is new in this release' heading
- Improved awk pattern to properly extract changelog sections
- Support both [vX.Y.Z] and [X.Y.Z] version formats in CHANGELOG
- Removes unnecessary app name and separator lines
Testing:
✅ worker-mobile-app: Extracts content from apps/mobile/apps/staff/CHANGELOG.md
✅ client-mobile-app: Extracts content from apps/mobile/apps/client/CHANGELOG.md
✅ Handles [v0.0.1-m3] format correctly
Fixed workflow failure by ensuring only data goes to stdout, not informational messages. Also added support for version format X.Y.Z-suffix in addition to X.Y.Z+build.
Add CI/CD and release automation assets: new GitHub Actions workflows (backend-foundation, hotfix-branch-creation, mobile-ci, product-release, web-quality), shell scripts for version/tag/release-note extraction and release-summary generation (.github/scripts/*), and a Pull Request template. Implements hotfix branch creation from tags, automatic tag name generation, version extraction from pubspec.yaml, CHANGELOG-based release notes extraction, selective mobile CI (detects changed files, builds and lints only affected Dart files), backend service test dry-runs, and automated GitHub release creation with summaries.
