Subject: [PATCH] ci: rust-cache was caching nothing, it needs workspaces

Swatinem/rust-cache@v2 was used with no workspaces input. The action looks for
one Cargo workspace at the checkout root, and nothing is checked out there:
every checkout in these jobs uses path:. The action logged "could not find
Cargo.toml" and carried on WITHOUT failing, so the job rebuilt everything from
scratch on every run while the log said the cache step succeeded.

Every workspace the job actually builds is now named. Where the job also builds
the sibling busbar checkout, that is listed too: it is by far the larger of the
two builds and the one worth caching most.
