The test and format scripts regenerated mfer/mf.pb.go whenever
mfer/mf.proto looked newer by mtime, which a fresh checkout often causes,
so make check could rewrite a committed file and needed protoc. Nothing
regenerates it any more except make generate (script/generate), which
refuses to run unless protoc 33.4 and protoc-gen-go v1.36.11, the
versions that wrote the committed file, are on PATH, and records the
hash of mf.proto in mfer/mf.proto.sha256. A Go test compares that hash
with mf.proto and fails, naming make generate, when they differ. The
mtime rule, the unused protoc-gen-go v1.28.1 install rule, make clean's
deletion of mf.pb.go and the Dockerfile's touch workarounds are removed.

script/lint now builds only the lint stage of the main Dockerfile
(docker build --no-cache --target lint), whose build runs the linter, so
a successful build is a clean lint. It is uncached because a cached
build runs no linter, and a trap removes the image it tagged; the tag
carries the process ID so concurrent runs do not collide. The lint stage
calls golangci-lint directly, since make lint now needs Docker. Nothing
installs or runs golangci-lint on the host any more: bootstrap and the
Makefile drop the install, and script/fmt drops golangci-lint run --fix.

FuzzNewManifestFromReader fails when the parser returns both or neither
of a manifest and an error, or allocates more than a fixed multiple of
its input and the decompressed data it may read, plus room for the
decoder's window buffers. make test runs the seed corpus; make fuzz
fuzzes for one minute.
Parser bug: MaxDecompressedSize did not bound decompression; the zstd
decoder decoded a payload under 128 KiB in full before the LimitReader
read any of it. It now decodes only what the LimitReader reads and
refuses windows over the 8 MiB mfer writes with. Seeds: a frame claiming
8 GiB, two frames together over the limit, empty frames with growing
windows.

A bare `docker build .` served the Dockerfile's check steps from the
layer cache on an unchanged tree and exited 0 without running them.
script/cibuild now computes the version on its own line and runs the
same build command as script/docker and the shared policy, --no-cache
included, so every CI build runs the checks. README.md describes
script/cibuild accordingly.
Model: opus-5-5
.dockerignore now sends .git but not .git/config, which can hold a
credential and which git describe does not need. The build stage stamps
main.Gitrev from the VERSION build argument when one is given, otherwise
from git describe --tags --always, and fails if .git is present and no
version comes out. git there trusts /src whoever owns it, since a
context sent as a tar archive keeps its files' owners. script/docker is
replaced by the canonical copy, which passes VERSION; bin/gitrev.sh uses
--tags too, so every entrypoint stamps the same value for a clean
commit.
Model: opus-5-5
script/test now runs go test -timeout 30s -race -cover ./..., quiet on success and rerunning verbose on failure. -race exposed a data race on the process-global apex/log logger: Init reconfigured it on every CLI run while other goroutines logged through it. internal/log now mutates the global under the write lock and reads it under the read lock; WithError is dropped because its Entry logged outside that lock, and run() reports a failed command's error via log.Errorf instead (still shown under -q). The corruption fuzz test is scaled to 1500 files / 100 iterations to fit the budget under -race; it pins the same claims at reduced breadth. Independent review ran the Docker lint gate uncached.

Adds .prettierrc and .prettierignore, a single script/prettier entrypoint shared by fmt and fmt-check so the two cannot drift, and prettier 3.9.6 pinned by yarn.lock integrity hash.
Markdown formatting is now gated in the authoritative Docker build via a new mdfmt stage, since the golangci-lint image has no node. REPO_POLICIES.md is ignored so local tooling cannot drift it from upstream.
Removes the || true that made the previous prettier invocation unable to fail.
