Rollback handlers now receive step context

Patch Changes

• #14318 f32e9c1 Thanks @vaishnav-mk! - Add step context to Workflows rollback handlers

  Rollback handlers now receive the original step context under ctx, making ctx.step.name, ctx.step.count, ctx.attempt, and the resolved step config available during rollback. The legacy stepName field remains available and is equivalent to ${ctx.step.name}-${ctx.step.count}.

  rollbackConfig is now limited to retry and timeout settings, matching the behavior supported by rollback handlers.

• #14314 5c3bb11 Thanks @harryzcy! - Bump esbuild to 0.28.1

  This update includes several bug fixes from esbuild versions 0.27.3 through 0.28.1. See the esbuild changelog for details.
