* fix: only use containers-storage when explicitly requested
- containers-storage is no longer part of automatic image resolution; it's used only for `--from containers-storage`, the `containers-storage:` scheme, or `default-pull-source: containers-storage` (now an accepted value). Opening a store runs full graph driver init (mounts, locks, store writes), which is too invasive as a probe on every plain image reference.
- rootless stores must be read from inside the builder's user namespace (`podman unshare syft ...`), documented in the README.
- the `containers_image_openpgp` tag is now applied to unit/integration tests and lint, so dev tooling compiles the same provider that ships.
- containers-storage CI runs through `make containers-storage-test` and covers both vfs and overlay stores.

* fix: exclude cgo btrfs driver and unmount overlay store in cleanup
- cgo-enabled linux builds (`-race` tests, lint) compile go.podman.io's btrfs graph driver, which needs libbtrfs headers. Add `exclude_graphdriver_btrfs` alongside `containers_image_openpgp` everywhere the tag is set; release builds are `CGO_ENABLED=0` and never included it.
- the overlay driver bind-mounts its graphroot inside the rootless user namespace, so the containers-storage test unmounts it before removing the store, and cleanup no longer fails the run.
