devcontainer(just): replace INSTALL_ALL with JUST_RECIPE build arg

- Dockerfile: switch ARG from INSTALL_ALL to JUST_RECIPE and run the specified just recipe during build when JUST_RECIPE is set.
- Justfile: update docker/macos "build-all" targets to pass JUST_RECIPE=install-all.
- DevContainer configs: update example build args in .devcontainer/*/devcontainer.json to show JUST_RECIPE.
- CI/docs: update GitHub Actions input description and docs/build.md / .devcontainer/just/README.md to reference JUST_RECIPE.

Allows running arbitrary just recipes at image build time (e.g. install-all) instead of a boolean INSTALL_ALL flag.
