Why

The action covers common buildx inputs but lacks outputs and build-contexts, which are important for multi-output builds and monorepo/multi-context Dockerfiles.

Verified

action.yml lists context/file/tags/build-args/secrets/ssh/platforms/cache/provenance/sbom/extra-args but no outputs or build-contexts input.
No existing docker-build-action issues are filed.
Upstream docker/build-push-action supports these as first-class inputs.

Build

Add newline-list inputs for outputs and build-contexts and map them to --output / --build-context.
Test shell quoting and multiple values.
Update README/MIGRATION examples.
