* [workflow o11y] rebase on latest main and keep targeted UI/builders changes
Rebase the branch intent onto latest main by preserving web-shared UI refactors and builders base-builder updates while taking main for hydration and data-fetching behavior elsewhere.

* [workflow o11y] align web-shared hydration revivers with main
Revert the hydration reviver delta for URL, URLSearchParams, and Headers so web-shared matches main behavior while keeping the targeted UI/builders-only scope on this branch.

* [workflow o11y] restore PR #1017 detail-panel decoupling
Bring the web-shared trace/detail panel files back in sync with main so PR #1017 behavior is preserved and not regressed on this branch.

## Summary
- Replace Next.js App Router with React Router v7.13.0 framework mode (Vite-based), eliminating the large `next` dependency from the web, CLI, and workflow metapackages
- Serve the web UI in-process from the CLI via Express instead of spawning `next start` as a child process
- Switch RPC transport from JSON to CBOR to preserve binary data types across the wire
- Replace `nuqs` URL state management with React Router's `useSearchParams`
- Replace Next.js server actions with an RPC resource route (`/api/rpc`) and a thin CBOR-based client
## Motivation
The `next` package is ~300MB installed and was the single largest dependency in the monorepo. It also required spawning a separate child process from the CLI to run the o11y web server, adding complexity around process lifecycle management, port readiness polling, and environment variable forwarding.
With React Router framework mode, the web package builds to a standard Express-compatible server bundle that the CLI can import and serve directly in its own process.
## What changed
**Framework swap (`@workflow/web`):**
- `next.config.ts` / `postcss.config.mjs` → `react-router.config.ts` / `vite.config.ts`
- `src/` directory → `app/` directory (React Router convention)
- `src/app/layout.tsx` + `layout-client.tsx` → `app/root.tsx`
- `src/app/page.tsx` → `app/routes/home.tsx`
- `src/app/run/[runId]/page.tsx` → `app/routes/run-detail.tsx`
- Path alias `@/` → `~/`
- Removed all `'use client'` / `'use server'` directives
**Data transport:**
- Server actions → RPC resource route at `/api/rpc` with CBOR encoding
- CBOR preserves `Uint8Array` and other binary types natively (no base64 overhead)
- Stream reading → dedicated `/api/stream/:streamId` resource route
**URL state:**
- `nuqs` (`useQueryState`) → `useSearchParams` from `react-router`
**Fonts:**
- `next/font/google` → Geist `.woff2` files referenced directly from `node_modules/geist` via `@font-face` in CSS
**CLI integration (`@workflow/cli`):**
- `import('@workflow/web/server').then(m => m.startServer(port))`
- No child process, no readiness polling, no cleanup handlers
**Radix UI compatibility:**
- `onSubmit` preventDefault on `AlertDialogContent` and `SheetContent` to prevent Radix's internal `<form method="dialog">` from triggering React Router route actions
- Catch-all action on root route for any stray POSTs
## Dependencies removed
- `next`, `swr`, `nuqs`, `@tailwindcss/postcss`
## Dependencies added
- `react-router` / `@react-router/dev` / `@react-router/node` / `@react-router/express` (all `7.13.0`)
- `express`, `vite`, `@tailwindcss/vite`, `cbor-x`, `isbot`, `cross-env`
- `geist` (devDep)
