wai-ui: the room frame is marked noindex (a frame of a page, not a page)

wai-ui: unique served names, room services by kind, CI, and a pending statement's values checked once it is whole
- runtime.mjs gives every runtime file a unique served name (wai-ui-<name>, wai-ui-room-<name>.js, wai_ui_room_moq, wai_ui_room_live): the WAI site fingerprints assets keyed by basename, and an export's vendor/ carries the same layout; - a room widget takes the room service for its kind (data-service-live, -watch, -show) when the page names one; - WAI's value rules (a poll's options and seconds, a show's audience, a watch room's source) wait for a pending statement to complete, as the line language's own errors do: a poll's `seconds` reads 2 before 20, and the poll no longer leaves the page for that chunk (found by the end-to-end run; a unit test now streams every recording a character at a time and requires that no widget, once shown, goes); - .github/workflows/wai-ui.yml: tests, clippy and the wasm32 surface, the line language's verifier and its mutations, the page modules (linux); Create in the browser (macos); - the e2e drives a WAI site build with --site; - wai-ui cites joule-ui's spec by its file (joule-ui/SPEC.md §N).

wai-ui: WAI's widgets for joule-ui, and Create (describe an app, watch it build, export it)
- a joule-ui registry of WAI widgets: App, Room, WatchTogether, Show, Player, Chat, Poll, Participants, Receipts, EnergyMeter, Text; each room kind accepts only the widgets its room service keeps (a watch room holds no Chat and no Poll), so a line that asks for more is refused disallowed-child at its line; - WAI's own rules on an app (one room, a poll's options, a show's audience, a watch room's source) and the room an app needs; - the guide a model writes against, made from the registry; - export: the one writer of a starter project (the program, its tree, the room service's configuration, the page, a check that is its build, a development front, README, AGENTS.md, the runtime under vendor/; no key); - the page's WebAssembly surface: the program streamed into snapshots, and every action sealed into the page's hash-chained log through joule-ui-interaction; - wai-ui mcp: an MCP server and a loopback bridge, so a person's own coding agent drives Create; - web/: the streaming renderer (keyed, so a joined room survives the next chunk), the components over the room client in a same-origin frame, the Create page with its three model sources (the visitor's own model and key, their coding agent, a recorded stream), the exported app's page, and the runtime layout; - e2e/: Create in a browser against a real room service and relay.

joule-ui: the line language (SPEC §11), a streaming ingest into validated widget trees
joule-ui takes in OpenUI Lang 1.0 the way it takes in A2UI: a model writes a surface as a program, one widget a line, and joule-ui-lang builds a widget tree against the host's registry as the program streams. After every chunk a snapshot holds the tree as far as it can be built, each widget checked by joule-ui's own validate, and every error with its source line and reason code. State, queries, operators, conditionals, built-in functions and sequences of actions are parsed and refused not-declarative. A canonical writer turns a tree back into the language; it parses back to the same tree. - joule-ui-core: WidgetSchema::positional, the order a positional call passes props in (SPEC §3); absent from the wire form when undeclared. - joule-ui-interaction: begin_interaction and Pending::finish, the lifecycle's three phases in two steps for a host whose handler is asynchronous (SPEC §6); run_interaction is built on them and seals what it sealed before. - conformance/lang/v1: L1 statements, L2 ingest, L3 streaming, L4 the canonical form, L5 refusals, with an independent Python verifier written from §11. - docs/create.md: the design of Create.
