fix(codeaf): build furrow from source and hand it over in CODEAF_FURROW
The package used to fetch the Agent-Field/furrow release asset and stage it for
go:embed, which is what `make build` does. Those bytes are a stock glibc build
that no Nix phase ever touched, so the copy codeaf writes out to
~/.codeaf/bin/furrow-0.1.0 cannot start here: NixOS answers "Could not start
dynamically linked executable" and names stub-ld. Every furrow verb the package
offers was dead with it.

Staging a rebuilt furrow was not an option. Upstream's fetcher hashes what it
stages against internal/furrowbin/pin.json and refuses anything else, and
patching the downloaded asset changes its hash. So this stages nothing, and
./furrow.nix builds the pinned version from source instead. The wrapped codeaf
passes it through CODEAF_FURROW, which internal/furrow reads before it looks at
the embedded copy, so the go binary carries no furrow at all (63 MB, was 67 MB)
and nothing unpatched is written to the state root.

furrow is Rust, not Go, and rusqlite bundles sqlite, hence the build time. Its
test suite wants a filesystem that supports user.* xattrs; the sandbox /tmp is
tmpfs and answers EOPNOTSUPP, which takes out the fixture of all 54 cli tests at
tests/cli.rs:48 and one lib test with it. The unit tests run, minus that one.

Verified with nix build .#codeaf: `codeaf --version` reports 0.7.1, the wrapper
sets CODEAF_FURROW to the store furrow, that furrow prints `furrow 0.1.0`
against store glibc, and it sits in the codeaf output's references so a gc
cannot pull it out from under the wrapper. Not verified on darwin, no builder.
