fix(commit0): drop the forked agent-layer Dockerfile, build through the shared phased pipeline (#778)

* fix(commit0): drop the forked agent-layer Dockerfile, build through the shared phased pipeline

Dockerfile.agent-layer-commit0 re-implemented the SDK's base-image-minimal
setup (runtime packages, user creation, ACP install) instead of inheriting
it, and had silently drifted onto stale/dead ACP pins (codex-acp pointed at
the abandoned @zed-industries pre-migration package). The SDK's
base-image-minimal target already handles raw upstream apt-based images
(exactly commit0's case) via its package-manager case statement — this is
the same mechanism SWE-Bench already uses successfully against its own raw
upstream (docker.io/swebench/*) base images.

Route commit0 through the same three-phase pipeline as SWE-Bench:
builder -> base-image-minimal -> Dockerfile.agent-layer. Image tags now use
the shared get_phased_image_tag_prefix() scheme (content-hash-qualified)
instead of a commit0-only Dockerfile-hash prefix.

Relates to OpenHands/software-agent-sdk#4643 (opportunity 1). #4805's
cross-repo Dockerfile/acp_providers.py parity test cannot reach into this
repo, which is why deletion (not re-pinning) is the fix.

* ci(commit0): expose --max-retries in build-commit0-images.yml

Mirrors build-swebench-images.yml's existing max-retries input/env/CLI
wiring. commit0's build_images.py already accepts --max-retries via the
shared args parser (default 3); the workflow just never exposed it.
