feat(wfe-core): add workflow executor with result processing and error handling
...
WorkflowExecutor: acquire lock, load instance, run steps, process
results, persist, release lock. StepRegistry for resolving step types.
ResultProcessor handles: next, outcome, persist, branch, sleep,
wait_for_event, poll_endpoint. ErrorHandler implements Retry (with
max_retries), Suspend, Terminate, and Compensate behaviors.

feat(wfe-core): add fluent workflow builder API
...
Owned-self builder pattern (no lifetime parameters). WorkflowBuilder
chains start_with/then/end_workflow to produce WorkflowDefinition.
StepBuilder supports: name, id, on_error, compensate_with, then,
then_fn, wait_for, delay, if_do, while_do, for_each, saga, parallel.
ParallelBuilder for branching with join semantics. InlineStep for
closure-based steps. Step config stored on WorkflowStep.step_config.

feat(wfe-core): add step primitives for workflow control flow
...
12 step primitives implementing StepBody: DecideStep, IfStep, WhileStep,
ForEachStep, SequenceStep, DelayStep, WaitForStep, ScheduleStep,
RecurStep, PollEndpointStep, SagaContainerStep, EndStep.
Each primitive handles its state machine via persistence_data and
branch creation for container steps.

feat(wfe-core): add test support with in-memory providers and test suites
...
InMemoryPersistenceProvider, InMemoryLockProvider, InMemoryQueueProvider,
InMemoryLifecyclePublisher behind test-support feature flag.
Shared test suite macros: persistence_suite!, lock_suite!, queue_suite!
that run the same tests against any provider implementation.

feat(wfe-core): add models, traits, and error types
...
Core domain models: WorkflowInstance, ExecutionPointer, WorkflowDefinition,
WorkflowStep, Event, EventSubscription, ScheduledCommand, ExecutionError,
LifecycleEvent, PollEndpointConfig. All serde-serializable.
Provider traits: PersistenceProvider (composite of WorkflowRepository,
EventRepository, SubscriptionRepository, ScheduledCommandRepository),
DistributedLockProvider, QueueProvider, SearchIndex, LifecyclePublisher,
WorkflowMiddleware, StepMiddleware, WorkflowRegistry.
StepBody trait with StepExecutionContext for workflow step implementations.
WorkflowData marker trait (blanket impl for Serialize + DeserializeOwned).

chore: scaffold workspace with nextest and docker compose
...
Workspace with 6 crates: wfe-core, wfe-sqlite, wfe-postgres,
wfe-opensearch, wfe-valkey, and wfe (umbrella). Nextest profiles
for default, integration, and CI. Docker compose for PostgreSQL,
Valkey, and OpenSearch integration tests.
