Subject: [PATCH] fix: keep .git in build context so server Dockerfile can
 stamp commit hash

The 1.0.0 release added .dockerignore which excluded .git. server/Dockerfile
uses --mount=type=bind,source=.git to stamp the latest server commit into
the image (added in #1517), and BuildKit honors .dockerignore for bind
mount sources, so fresh builds fail with:

  failed to compute cache key: ... "/.git": not found

The bind mount approach never bakes .git into a layer, so keeping it in
the build context is safe.

Fixes #1702
