@webframp/hashicorp-vault: empty KV engine causes 'data.data.keys is not iterable' on vault put

After upgrading @swamp/kubernetes from 2026.05.27.2 to 2026.06.04.1 via swamp extension pull @swamp/kubernetes --force, all existing models fail with:

Last upgrade toVersion "2026.05.27.2" does not match model version "2026.06.04.1" for model type "@swamp/kubernetes/node"

The extension's upgrades array in each model type (e.g. node.ts:225) only declares an upgrade toVersion: "2026.05.27.2". There is no entry for toVersion: "2026.06.04.1", so swamp's upgrade system rejects the version mismatch.

Steps to reproduce

Have models created at @swamp/kubernetes 2026.05.27.2
swamp extension pull @swamp/kubernetes --force (pulls 2026.06.04.1)
Run any model method — fails with the version mismatch error

Additional issue: no CLI command to upgrade model typeVersion

There is no swamp model upgrade command. The only workaround is to manually edit the typeVersion field in each model YAML file, which doesn't work anyway because the upgrade system still rejects the mismatch. Models created at 2026.05.27.2 are effectively stuck.
