chore(work): decompose product-analytics-channel epic

Generated 1 epic + 9 stories under docs/work/epics/ from the approved
PRD docs/work/prds/product-analytics-channel.prd.md. Stories follow the
sequencing hints from the PRD (brand+wrapper → manifest+wireUseCase →
assertFeatureConformance → BindContext+ESLint → React provider → docs).
Ready for `pnpm work dispatch --execute` to begin implementation.

+title: Add React provider to @repo/core-analytics
+type: technical-story

+## Goal
+
+Add a `./react` subpath export to `@repo/core-analytics` containing `<AnalyticsProvider value={IAnalytics}>` and `useAnalytics(): IAnalytics`. `useAnalytics()` throws a clear error when called outside a provider. No auto-wired router events.
+
+## Why
+
+Server-side use cases receive analytics through `BindContext.analytics`. Client-side components need an equivalent contract surface so `analytics.track(...)` reads the same whether called from a use case or a React component. The provider bridges `IAnalytics` from DI land to React's context tree without coupling consumers to a specific vendor.
+
+## Done when
+
+- `@repo/core-analytics/react` subpath exports `AnalyticsProvider` and `useAnalytics`.
+- `useAnalytics()` throws a named error (`AnalyticsContextError` or similar) when called outside `<AnalyticsProvider>`.
+- React Testing Library test: render a child inside `<AnalyticsProvider value={recordingAnalytics}>`, child calls `useAnalytics().track("test.event")`, assert `recordingAnalytics.tracked` contains the event.
+- All gates pass.
+
+## In scope
+
+- `packages/core-analytics/src/react/analytics-provider.tsx` + `useAnalytics.ts` (or colocated).
+- `packages/core-analytics/src/react/index.ts` — subpath barrel.
+- `package.json` `exports` map: `"./react": "./dist/react/index.js"` (or equivalent for the build config).
+- React Testing Library test.
+
+## Out of scope
+
+- Auto-wiring Next App Router or TanStack Router route-change hooks (deferred per PRD).
+- SSR hydration concerns — provider is a pure context wrapper; consumers handle hydration.
+
+## Tasks
+
+- [ ] Add `AnalyticsProvider` + `useAnalytics()` to `packages/core-analytics/src/react/`, wire `./react` subpath export in `package.json`, write React Testing Library test using `RecordingAnalytics` asserting `track` flows through context — all gates pass on this commit.
