build: declare sibling crates by registry version

Sibling crates were declared with out-of-tree `path` dependencies, so this
manifest resolved only when several repositories happened to be checked out
side by side. A standalone clone failed at dependency resolution -- which is
why every workflow had to clone the siblings first, and why automated
dependency updates could not run against Cargo manifests here at all.

Each sibling is now declared by its published version. A development
workspace still builds them from source, through a `[patch.crates-io]`
entry in a Cargo config that lives outside this repository, so nothing here
carries a path that only exists in one working copy.

- drop the sibling checkout steps from the workflows
- enable the cargo ecosystem for automated dependency updates
