feat(studio): Object Designer protocol — field editor, relationship mapper, ER diagram, object manager schemas

[Copilot]

Defines the full spec protocol for the Object Designer experience in Studio — visual field editing, relationship mapping, ER diagrams, and unified object management. Updates roadmaps with refined implementation phases.

New: packages/spec/src/studio/object-designer.zod.ts

16 Zod schemas composing ObjectDesignerConfigSchema:

• Field Editor — inline editing, drag-reorder, 6 property panel sections (basics/constraints/relationship/display/security/advanced), field grouping, batch ops, pagination at 50+ fields
• Relationship Mapper — drag-to-create for lookup/master_detail/tree types, reverse relationships, cascade warnings, configurable line styles per type
• ER Diagram — 4 layout algorithms (force/hierarchy/grid/circular), node display with field list + type badges, minimap, zoom 0.1x–3x, click-to-navigate, drag-to-connect, export PNG/SVG/JSON, orphan hiding
• Object Manager — table/card/tree display modes, search + filter (package/tags/field types/relationships), quick-preview tooltips, stats summary, comparison mode
• Object Preview — 8-tab detail view (Fields, Relationships, Indexes, Validations, Capabilities, Data, API, Code)

import { defineObjectDesignerConfig } from '@objectstack/spec/studio';

const config = defineObjectDesignerConfig({
  defaultView: 'er-diagram',
  erDiagram: { layout: 'hierarchy', hideOrphans: true },
  fieldEditor: { showFieldGroups: true, batchOperations: true },
  objectManager: { defaultDisplayMode: 'cards', showERDiagramToggle: true },
});

Tests

46 tests covering all schemas — defaults, partial overrides, validation rejection. All 197 test files / 5,363 tests passing.

Roadmap updates

• ROADMAP.md Phase 8.1 expanded with ER diagram and object manager line items; metrics updated
• apps/studio/ROADMAP.md Phase 1 refined into sub-tasks 1.0–1.1d with protocol marked complete
