✅ Outcome

• Forward ambient Convex deployment auth env from standalone migrate and aggregate command handlers for prod-target runs.
• Cover migrate up/status/cancel and aggregate backfill/prune with regression tests.
• Add a patch changeset for the package release.

🏗️ Design

• Chosen seam: thread getConvexDeploymentCommandEnv() through standalone command handlers and extend runAggregatePruneFlow() to accept forwarded env.
• Why not quick patch: fixing only one branch would leave the same regression in sibling standalone paths.
• Why not broader change: keep createBackendCommandEnv() default wipe intact so local dev/codegen behavior stays unchanged.
