// Package canvas — public re-export of withState for cross-package tests.
//
// The package-internal withState attaches *CanvasState to a context so
// GetStateFromContext can retrieve it. It is unexported because the
// production call site is exactly one: the orchestrator's compile entry
// (compile.go). External callers should never need to inject state
// themselves.
//
// Cross-package unit tests (e.g. internal/agent/component/*_test.go) do
// need a way to set up a state for component Invoke() calls. This file
// exposes a single thin re-export — WithState — that the test code in
// other packages can call. Production code paths are not affected:
// nothing in the production binary calls WithState; the orchestrator
// keeps using the unexported withState directly.

// (production code uses the unexported withState via compile.go).
// Both entry points delegate to runtime.WithState.
