Add managed Trrack provenance APIs

[JackWilb]

Summary

• add useRevisitTrrack for React stimuli and Revisit.createTrrack for website/iframe stimuli
• subscribe before stimulus layout effects, capture the initial node plus every apply/undo/redo/direct traversal, and clean up listeners on unmount or navigation
• send source-timestamped traversal history through a provenance-only store action instead of coupling provenance writes to answer validation
• keep manual provenance submission and graph-only replay as deprecated compatibility paths for existing studies and historical data
• migrate built-in response/Vega tracking and all official React, HTML, and Svelte examples to the managed APIs
• regenerate config schemas and add lifecycle, transport, store, replay, and browser-demo coverage

Root cause

reVISit could only observe graph snapshots that a study explicitly submitted. A private Trrack instance could therefore apply, undo, or redo without the platform seeing the transition, and graph node creation order alone cannot reconstruct revisits to existing nodes.

The managed APIs make reVISit responsible for instance creation and observation while leaving study state and action definitions in study code.

Compatibility

• Existing setAnswer({ provenanceGraph }) and Revisit.postProvenance(...) integrations continue to work through the store-ingestion fallback and are marked @deprecated.
• Historical provenance without traversal events continues through the graph-only replay fallback, which is also marked @deprecated.
• No historical timing is fabricated and no dependency is added.

Stacked dependency

This PR targets codex/issue-1284-trrack-replay and must merge after #1305. It builds on #1305's traversal data model and replay compatibility work, then reduces its store-ingestion recording to the deprecated manual-integration fallback.

Validation

• yarn generate-schemas
• yarn typecheck
• yarn lint
• focused Vitest suite: 110 passed
• yarn unittest --run: 1,859 passed, 1 skipped
• yarn build
• git diff --check

The updated Playwright demo coverage will run in CI; it was not run locally per the repository testing policy.

Closes #659

Can we pass through in StimulusParams?
