Add checked React field bindings and Web Studio factories

Replace opaque props with checked generic presentation contracts and lazy typed
interface references. Generate readonly/writable field APIs and component checks.

Preserve CRDT editing through explicit resolved getter/setter contracts, binding-
fenced delta RPCs, native watches and replica-aware field adapters. Custom setters
retain semantic writes; storage snapshots never grant write authority. Cover
concurrent edits, lost acknowledgements, readonly contracts and authorization.

Add receiver-free static factory dispatch, state-field binding shorthand, and
conformance-based creation. Migrate TODO, editable scaffolds and authoring guides.
Verify language/codegen, SDK, RPC, browser lifecycle, local scaffolds, production
browser bundling and CRDT persistence with temporary PostgreSQL.
