Add graph-aware React controls with stable asynchronous selection

Add typed command/live bindings, Choice and Toggle, CRDT text wrappers, and explicit browser-local controls. Migrate Reader and current example inputs. Enforce editable-control authoring checks in the React artifact backend.

Command controls display query observations, permit one local execution at a time, and delay pending feedback for 200 ms. Include keyboard, focus, shadow-root, top-layer popup, rejection/no-op, native-field eligibility, and IME coverage.

Verified SDK builds and tests, synchronous-editing browser qualification, Reader/Tasks qualification, presentation-mount qualification, and the review-dashboard browser test. Monorepo formatting and lint pass.

The full composition qualification stops at the unchanged combined-to-review workspace fixture transition: STORAGE_MODEL_CHANGED from changed/removed stored conformance owners. Its dashboard browser test passes when run directly.
