feat: continue tree rust family cutover

- add rust renderer/state-family scaffolds and inline compat host thinning for page tree, file tree, and picker - route tree/filetree preflight, file projection, resource artifact, and stream delta contracts through rust plans - preserve canonical move-order validation, file-tree search projection, and related frontend/runtime regression coverage
