Add a discoverable '+ Add transform' / '+ filter/aggregate/...' CodeLens in the
spec editor that scaffolds field-typed transform[] steps, with a type-to-filter
completion on the same catalog as an accelerator. New pure core
(spec-data-transforms): step-slot and view-site classification, the field-typed
catalog, and comma affixing. Deliberately the one home the schema leaves bare —
inline channel transforms and the transform key stay with the JSON schema.
Rename the composition toolbar menu Transform -> Compose so it reads distinctly
from a data transform. Deferred (recorded at their sites): extract a shared
cursor-lens skeleton across the two installers; a shared completion replace-range
helper (now 3 sites); params scaffolding as the sibling feature.
Drag a view's box (or Alt+up/down) to reorder it within its container; drag onto another view's edge to pair the two in a new row/column, move across containers, or insert. Each leaf shows a glyph of its mark type.
Core: spec-restructure.wrapViews (wrap, with flatten-to-insert, collapse, and data-pin invariants) and spec-insert.moveViewTo; the editor applies every drag as one undoable edit via AppStore.composeRequest, keeping the editor the single text source.
