chore(spec): regenerate the artifacts the new build-progress exports move, and declare the changeset

`check:generated` proved exactly five stale: api-surface, export-origins, declaration-map,
the rendered reference pages, and the unknown-key strictness ledger. Regenerated only those.

api-surface reads 6 added / 0 removed on `./ai` — a purely additive published surface, which
is what the `minor` and the `Clause-②: yes (widening)` declaration record.

+
+**Declare the build-progress PHASE vocabulary on `@objectstack/spec/ai`.**
+
+The `data-build-progress` stream frame has shipped as prose only: `AIToolContext.onProgress`
+documents the channel and its example carries a `phase`, but nothing ever declared which
+phases exist. Consumers filled that gap by guessing, and a guess here is not merely
+unlabelled — the objectui chat panel coerces any value it does not recognise to `structure`,
+which renders a "still building" spinner, so a build turn that has finished and moved on to
+verifying itself keeps claiming to be building.
+
+New exports (additive; nothing removed or renamed):
+
+- `BUILD_PROGRESS_PHASES` / `BuildProgressPhaseSchema` / `BuildProgressPhase` — the CLOSED
+  phase vocabulary: `structure`, `data`, `verify`, `done`, in lifecycle order. An
+  out-of-vocabulary value is refused, and the refusal names the accepted set.
+- `BuildProgressFrameSchema` / `BuildProgressFrame` — the frame's FLOOR: a required `phase`
+  plus an optional `hop` (which post-apply verification hop) and `tool` (the tool that hop is
+  running). Deliberately loose, not strict: the presentation fields the chat panel already
+  reads ride the same frame and belong to it, so a strict schema here would refuse every
+  frame shipping today.
+- `BUILD_PROGRESS_FRAME_TYPE` — `'data-build-progress'`, the one literal both ends select on.
+
+Producers emit these frames from the agent loop rather than from the applying tool: a tool's
+`ctx.onProgress` handle dies when the tool returns, and the verification window opens after
+it does. Consumers should compare phases by value and treat every phase as optional — a turn
+that seeds no sample data never reports `data`.
+
+Clause-②: yes (widening)

+
+Build-progress PHASE vocabulary for the `data-build-progress` stream frame
+(cloud#2172 ruling A).
+
+## Producer
+
+The cloud AI-studio **agent loop** — deliberately not the tool it just ran.
+A build turn applies its change through `apply_blueprint` / `apply_edit` and
+then keeps working: the loop spends a further POST-APPLY VERIFICATION window
+re-reading and re-seeding what it wrote (measured on cloud#1838: 111 seconds
+and 9 tool calls *after* `apply_blueprint` returned, one of them the
+registered `verify_build` tool — see `PLATFORM_TOOLS_BY_PACKAGE` in
+`../system/constants/platform-tool-names`). A tool's own `ctx.onProgress`
+handle dies when the tool returns, so a frame emitted in that window can only
+come from the loop. WHERE in the loop it is emitted is cloud#2172's decision,
+not this module's; what such a frame may SAY is declared here.
+
+## Consumer
+
+The objectui chat panel — `extractBuildProgress` in
+`packages/plugin-chatbot/src/mapMessages.ts`, which lifts the reconciled part
+onto `ChatBuildProgress` for the build panel in `ChatbotEnhanced.tsx`. That
+reader recognises a fixed set and coerces everything else to `'structure'`,
+which renders a "still building" spinner. So an UNDECLARED phase is not
+merely unlabelled — it reads as the wrong phase, and the user watches a
+build that finished two minutes ago still claim to be building
+(objectui#7388). The panel's per-phase COPY is objectui's to choose; this
+module fixes only the set of values it must be able to tell apart.
+
+## Channel
+
+Unchanged: the `data-`-prefixed custom part described on
+`AIToolContext.onProgress` in `../contracts/ai-service`, reconciled in place
+under a stable part id. This module adds the vocabulary that prose has always
+assumed and never declared; it moves no transport and renames nothing.
