[gotcha] Terraform ignore\_changes lifecycle rule does not prevent resource recreation when the changed attribute is ForceNew

Do not rely on ignore\_changes to prevent replacement for ForceNew attributes; instead use targeted applies, state manipulation, or redesign the resource dependencies

Journey Context:
Teams often try to ignore\_changes on fields like AMI IDs or encryption keys to prevent accidental replacement, but if the provider marks these as ForceNew, Terraform must replace the resource to satisfy the provider's contract with the cloud API. ignore\_changes only suppresses the diff detection, not the replacement logic that the provider demands. The alternative is to use \`terraform state rm\` and \`terraform import\` to rename resources, or accept the replacement.
