feat(ui): add Airtable-like view customization schemas

[Copilot]

The existing ListViewSchema lacked several primitives needed for Airtable-style view customization — per-view field visibility/ordering, record grouping, row density, column pinning/summaries, gallery/timeline configs, and view sharing semantics.

New schemas

• RowHeightSchema — compact | short | medium | tall | extra_tall
• GroupingConfigSchema — Multi-level record grouping with per-level sort order and collapse state
• GalleryConfigSchema — Cover image field, fit mode, card size, title/visible fields
• TimelineConfigSchema — Start/end date fields, group-by, color field, time scale
• ViewSharingSchema — personal | collaborative ownership with optional lock
• RowColorConfigSchema — Color rows by field value with explicit color map
• ColumnSummarySchema — Footer aggregation: count | sum | avg | min | max | count_unique | percent_empty | percent_filled | …

Enhanced existing schemas

• ListColumnSchema — Added pinned: 'left' | 'right' (frozen columns) and summary (footer aggregation)
• ListViewSchema — Added description, sharing, rowHeight, grouping, rowColor, hiddenFields, fieldOrder, gallery, timeline

Example

const view: ListView = {
  name: 'project_tracker',
  type: 'grid',
  columns: [
    { field: 'name', pinned: 'left', sortable: true, width: 250 },
    { field: 'status', width: 120, summary: 'count_unique' },
    { field: 'budget', align: 'right', summary: 'sum' },
  ],
  rowHeight: 'medium',
  grouping: {
    fields: [{ field: 'department', order: 'asc' }],
  },
  rowColor: {
    field: 'status',
    colors: { on_track: '#22c55e', at_risk: '#f59e0b', blocked: '#ef4444' },
  },
  hiddenFields: ['internal_id'],
  sharing: { type: 'collaborative', lockedBy: 'admin' },
};

37 new tests added (124 total view tests).

Pull request overview

This PR extends the UI view protocol (packages/spec/src/ui) to support Airtable-like list view customization, adding new Zod schemas for view metadata and per-view presentation controls and updating existing list view/column schemas accordingly.

Changes:

• Added new schemas for column summaries, row density, grouping, gallery/timeline configs, view sharing, and row coloring.
• Enhanced ListColumnSchema (pinning + footer summaries) and ListViewSchema (description/sharing + per-view field visibility/order + grouping/rowHeight/rowColor + gallery/timeline configs).
• Added/extended Vitest coverage for the new/updated schemas.

GroupingConfigSchema claims grouping "supports up to 3 levels", but the schema only enforces min(1) and will accept any number of grouping fields. Either enforce the stated limit with a .max(3) (or similar constraint), or update the description to avoid promising a limit that isn’t validated.

Suggested change

	fields: z.array(GroupingFieldSchema).min(1).describe('Fields to group by (supports up to 3 levels)'),
	fields: z.array(GroupingFieldSchema).min(1).describe('Fields to group by (supports multi-level grouping)'),
