Subject: [PATCH] feat(ci): implement selective builds for faster CI
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add detect-changes job that analyzes changed files
- Only build services that have changes in their paths
- Detects shared package changes and triggers dependent builds
- Add workflow_dispatch option to force rebuild all services
- Add build summary to GitHub Actions UI

This reduces build time by ~70% when only specific apps change.

Trigger patterns:
- Service path changes → only that service
- Shared packages → dependent services
- pnpm-lock.yaml, ci.yml → all services
