Subject: [PATCH] feat(go): exclude node_modules from fmt and add overrides
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add ! -path '*/node_modules/*' to all find commands in fmt and
fmt-check recipes. npm packages like flatted ship .go files that
break formatting checks in monorepos with ui/ directories.

Add JUST_GO_FMT_EXCLUDES env var so consuming projects can pass
extra find exclusions without forking the shared justfile.
