Presentation 4.0

[stephenwf]

IIIF Presentation 4

• upgradeToPresentation4() to ingest v2.1, v3.0 or v4.0 into a v4-compatible shape
• Traverse with v4 container support (Timeline, Canvas, Scene)
• normalize() with deterministic ID minting for missing IDs
• validatePresentation4() with traversal-first diagnostics (tolerant or strict)
• serializeConfigPresentation4 for native v4 output
• serializeConfigPresentation3 for strict v4→v3 downgrade (fails on unsupported v4-only constructs)
• pnpm run update-cookbook-v4 to refresh local fixtures/cookbook-v4 from preview cookbook v4

import {
  upgradeToPresentation4,
  normalize,
  validatePresentation4,
  serialize,
  serializeConfigPresentation4
} from '@iiif/parser/presentation-4';

const upgraded = upgradeToPresentation4(loadSomeManifest());
const report = validatePresentation4(upgraded);
const normalized = normalize(upgraded);
const serialized = serialize(
  { entities: normalized.entities, mapping: normalized.mapping, requests: {} },
  normalized.resource,
  serializeConfigPresentation4
);

Included is all the v4 3D manifests I could find. Also the v4 cookbook.
