IAC Plan

Preview an Infrastructure-as-Code change WITHOUT applying it. Runs `bin/iac-plan.sh`, which detects the repo's IaC tool (terraform, opentofu, aws-cdk, pulumi, helm, kubernetes, kustomize, ansible), shells out to the user's already-authenticated CLI, and renders a normalized add/change/destroy summary. READ-ONLY — it never mutates infrastructure. TRIGGER when the user says "terraform plan", "preview my infra change", "what will this deploy", "cdk diff", "pulumi preview", "show me the terraform diff", "dry-run the infra change", "what would terraform/tofu/cdk/pulumi do", "plan the infrastructure", "kubectl diff", "helm diff", "what does this deploy change", "/nyann:plan". DISAMBIGUATION — fire ONLY for IaC plan intent on a detected infra repo. Do NOT trigger on the bare word "plan": this is NOT project planning, NOT sprint/roadmap planning, NOT `sc:*` task planning, NOT Claude's ExitPlanMode / "make a plan" for code work. "plan a feature", "plan my week", "let's plan the refactor" → ignore. Require an infra signal (a tool name like terraform/tofu/cdk/pulumi/helm/kubectl, OR the word "infra"/"infrastructure"/"deploy", OR a detected `iac.tool` in the stack descriptor). With no infra signal, do NOT trigger. To apply the change after previewing, that's `/nyann:apply` (the iac-apply skill) — iac-plan never applies.
