feat: Update zinit-client dependency to 0.4.0

- Upgrade `zinit-client` dependency to version 0.4.0 across all
  relevant crates. This resolves potential compatibility issues
  and incorporates bug fixes and improvements from the latest
  release.

- Improve error handling and logging in `zinit-client` and
  `service_manager` to provide more informative feedback and
  prevent potential hangs during log retrieval.  Add timeout to
  prevent indefinite blocking on log retrieval.

- Update `publish-all.sh` script to correctly handle the
  `service_manager` crate during publishing.  Improves handling of
  special cases in the publishing script.

- Add `zinit-client.workspace = true` to `Cargo.toml` to ensure
  consistent dependency management across the workspace.  This
  ensures the correct version of `zinit-client` is used everywhere.
