v1.20.3

What's Changed

Fixed

• Workflow Bundler: further strengthening of the webpack_module_cache replacement logic, addressing regressions introduced by the fix in 1.20.1.
• @temporalio/langsmith: install Workflow-bundle rewrites via compiler.webpack so they work under non-hoisting node_modules layouts (e.g. pnpm hoist=false).
• @temporalio/langsmith: emit the LangSmith run fire-and-forget rather than awaiting it, removing a yield point that reordered commands under signalWithStart.
