Description

Terraform emits replace_because_cannot_update, replace_because_tainted, replace_by_triggers,
delete_because_no_resource_config, delete_because_count_index; Tirith reads actions and
ignores it. delete_because_no_resource_config is "a module was removed and it destroys
production", named precisely at plan time. Not present in older fixture plans — confirm against a
fresh Terraform version first. Turns a verdict into an explanation.

Research direction

Start by checking Tirith's handling of Terraform plan actions, then generate a plan with a fresh Terraform version to confirm the available action_reason values. Compare this with older fixture plans and trace where the actions field is read. Done means the relevant action_reason is exposed as part of the verdict explanation without breaking plans that lack it.
