phase 5: edge transforms, soleprint-ui rename, infra fixes

- pipeline edge transforms: stages can declare accepted_transforms,
  edges carry a transform dict, runner injects per-stage and nodes
  apply (e.g. invert_mask before edge detection); editable from UI
  via PUT /config/edge-transform
- rename mpr-ui-framework -> soleprint-ui (now an external package
  synced via .spr from /home/mariano/wdir/spr); add @vue-flow/core
  and uplot to detection-app so linked package resolves them
- Tiltfile guards kubectl context, k8s commands pin --context kind-mpr
- kind-config: gateway on hostPort 30080 (Caddy fronts mpr.local.ar)
- modelgen: pyproject.toml, .spr marker, dict default_factory support
