Subject: [PATCH 1/4] ci: serialize image builds into per-branch workflows to
 cut concurrent build cost

Collapse the three previous workflows (build_testnet, build_mainnet,
build_gpu) into one workflow per branch:

- build_develop.yml: devnet CPU -> testnet CPU -> devnet GPU -> testnet GPU
- build_main.yml: mainnet CPU -> mainnet GPU (with version git tag)

Steps run sequentially in a single job (one runner, one buildx-cloud
session, one Docker login), and a shared concurrency group prevents a
develop build and a main build from overlapping. Build steps use
`if: !cancelled()` so a failure in one image does not block subsequent
images, since the images are independent.

Subject: [PATCH 2/4] ci: prune buildx-cloud cache between CPU and GPU build
 pairs

The cloud builder's gcPolicy caps cache at 25GiB. After 2 CPU builds the
cache fills with non-GPU layers, then the GPU base (libtorch + CUDA)
cannot be extracted and the GPU build fails with "no space left on
device" inside /buildkit/data/runc-overlayfs/snapshots/.

Prune the builder cache right before the GPU pair so the CPU layers (which
the GPU builds cannot reuse anyway) are evicted. The two GPU builds still
share the freshly cached GPU base, so we keep within-pair cache reuse.

Subject: [PATCH 3/4] ci: split each image build into its own job for clearer
 run-graph view

Each image (devnet/testnet CPU+GPU on develop, mainnet CPU+GPU on main)
is now its own job, chained via `needs:` to keep them sequential. The
run-summary view shows one box per image instead of a single job with
nested steps, and individual builds can be re-run on their own.

Buildx-cloud cache stays shared across jobs because it lives on the cloud
builder (server-side), so layer reuse between adjacent builds is
preserved. The CPU-to-GPU prune still runs at the start of the first GPU
job to free the CPU layers from the cache cap.

Failure semantics unchanged: `if: !cancelled()` on downstream jobs lets
each build run independently of the previous one's outcome.
