Subject: [PATCH] apk: ship dolt-git-hook as a -hook subpackage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The hook binary was the one piece of this repo not in the apk — the
deployment's Dockerfile.git cloned the repo and compiled it from source
at a separately pinned revision (SRHT_DOLT_HOOK_REV), which meant a
second version pin to keep in lockstep, a build-time dependency on the
git host, and a full Go toolchain stage in the git image rebuild.

Add dolt-git-hook to the Makefile's BINARIES (same guarded target
pattern) and split it into a dolt.sr.ht-hook subpackage: the git.sr.ht
container needs only this 9 MB binary, not the 126 MB doltsrht service
the main package carries. The deployment can now apk-add the subpackage
at the same pinned version as the service.
