chore(release): bump workspace version to 0.4.1; canary base to 0.5.0

The [workspace.package] version (inherited by every crate via version.workspace)
lagged at 0.3.0 through the 0.4.0 release — bump it to 0.4.1, the release being
cut, and refresh the 8 workspace entries in Cargo.lock to match (CI builds
--locked).

Also advance the CI canary-base fallbacks (deb/rpm/flatpak/android/release
workflows + build-rpm.sh) from 0.3.0 to 0.5.0 so main/canary builds sort one
minor ahead of the latest stable line, per the documented channel convention.
