### Bug Description The `CRAFT_PROJECT_VERSION` depends on the rockcraft.yaml's `version` field and thus should be registered after the YAML is loaded. This should happen in https://github.com/canonical/rockcraft/blob/bdf64517487be2fac8fa28ddfe3919e08f9b3bde/rockcraft/lifecycle.py#L70 however, the callback does not seem to be working and this environment variable never gets loaded. ### To Reproduce Run `rockcraft --verbosity debug` on https://github.com/jnsgruk/zinc-k8s-operator/blob/main/rockcraft.yaml (originally reported by @jnsgruk in https://chat.charmhub.io/charmhub/pl/h9qytisgti8s3pu6yhe1pq8hpy). ### Environment Version: `0+git.bdf6451` ### rockcraft.yaml ```shell name: zinc version: 0.4.7 license: Apache-2.0 base: bare build_base: ubuntu:22.04 platforms: amd64: summary: Zinc is a lightweight search engine and alternative to Elasticsearch. description: | Zinc is a search engine that does full text indexing. It is a lightweight alternative to elasticsearch and runs in less than 100 MB of RAM. It uses bluge as the underlying indexing library. It is very simple and easy to operate as opposed to elasticsearch which requires a couple dozen knobs to understand and tune. It is a drop-in replacement for elasticsearch if you are just ingesting data using APIs and searching using kibana (Kibana is not supported with zinc.
