fix(ci): disable cancel-in-progress for build workflow

The concurrency group cancels all matrix jobs when a new commit lands,
causing most jobs (packaging, build, deps_check) to be cancelled before
completion. This makes CI results unreliably incomplete — only the 4
fastest-completing jobs show results (all failures), masking the actual
state.

Disabling cancel-in-progress ensures all matrix jobs complete fully and
the real results are visible, even if it means older runs complete after
a new one starts.
