Subject: [PATCH] chore(ci): cancel superseded workflow runs

Without a `concurrency` block, pushing three commits to a branch runs the whole
suite three times and pays for all three. The group is scoped to the ref so
different branches never cancel each other.

Deploy and release workflows use `cancel-in-progress: false`: interrupting one
mid-flight can leave a half-published artifact, so they queue instead.

Added a concurrency block to 2 workflow(s).
