vpctl 0.5.0

Added

1. Feature

   `infrastructure` manifest section with sizing profiles ( `small` , `medium` , `large` ) and per-component resource overrides for MongoDB, PostgreSQL, RabbitMQ, object storage, and Elasticsearch.

2. Feature

   `image sync --skip-existing` flag: checks if each image already exists on the target registry (via `docker manifest inspect` ) and skips it, to avoid redundant pull an push cycles.

3. Feature

   `image sync --cleanup` flag: removes local images ( `docker rmi` ) after each successful push, to free disk space on CI runners and local machines.
