WAC v2 scripts previously disabled bundle caching, forcing every execution to resolve windmill-client from node_modules at runtime (~74ms overhead per bun launch). This makes both the prebundle and execution paths WAC-aware by including WorkflowCtx/StepSuspend/setWorkflowCtx re-exports in the bundle, so the wrapper can import them from the cached bundle instead of node_modules. Benchmarked improvement: wac_inline_2 12→38 wf/s (3.2x), wac_seq_2 6→17 wf/s (2.8x) with no regression on plain bun scripts or flows.
