Module github.com/fission/fission -> github.com/hanzoai/functions (288 files). CRD API group fission.io -> hanzo.ai (67 files): functions.hanzo.ai, environments.hanzo.ai, httptriggers.hanzo.ai, messagequeuetriggers.hanzo.ai, joining apps.hanzo.ai under the one house group. Doc URLs preserved. Builds green. Matches the cloud contract: clients/functions, /v1/functions, App CR role "function". Remaining: fork the env images + the live CRD-group migration (demo-only today, low risk).
