Configure monorepo build: unified CI, local deps, .dockerignore

- Dockerfiles use monorepo root as build context
- common/ and core/ installed as local packages (no git+https)
- Client tarball built from local client/ dir
- Unified CI with change detection: common/core -> rebuild both
- Per-repo CI workflows removed
