Reintroduce --all option in n8n publish to activate all workflows

The idea is:

Reintroduce the --all option in the n8n publish CLI command to allow activating all imported workflows at once.

My use case:

After upgrading to n8n 2.3.4, the --all option is no longer available. Previously, we used the deprecated update command with --all to quickly activate workflows after importing them when setting up a new workspace.

Why this matters

  • Activating workflows individually takes ~4–5 minutes
  • Slows down workspace setup and CI/CD automation
  • Previously this was a simple one-step process

I think it would be beneficial to add this because:

Restoring the --all option would significantly improve deployment speed, as activating workflows individually takes considerably more time.
