Consolidate 5 standalone Ubuntu full-suite jobs into a single matrix. Rebalance Windows shards (6 to 5) by merging `unit c` with `unit coverage`. Rename Windows jobs to remove name collision between `windows` and `windows-acceptance` (the skipped job on PRs now shows a clean label). Keep acceptance matrix push-only.

Previous run showed `unit d-p` as the slowest shard at ~2m01s. Split into `unit d-g` (6 files, ~820 LOC) and `unit h-p` (4 files, ~848 LOC, includes the heavy `helpers_test.sh` and `parallel_test.sh`). Wall-clock target drops to ~1m per shard. Adds one runner, halves Windows completion time.
GitHub evaluates job-level `if:` before matrix expansion, so a skipped
job with a `${{ matrix.name }}` template leaks the raw template into
the PR checks UI. Removing the explicit `name:` lets GitHub auto-name
from the job id (`windows-acceptance` when skipped, `windows-acceptance
(a-e)` etc. when running).
