CDP acceptance

# Recipe: CDP acceptance tests on Cloudflare
#
# Use case: acceptance tests that boot the app under test and drive it via
# the Chrome DevTools Protocol — asserting on network calls, console errors,
# document counts, heap deltas. Offload to the shipped `cdp-acceptance` run,
# which boots the app in a container and attaches Browser Rendering over CDP.
#
# Mode: Action mode, await — a follow-up deploy gate needs the result inline.
#       See specs/04-gha-integration.md#await-sub-mode.
# Run:  cdp-acceptance — see specs/02-runs.md#4-cdp-acceptance.

# In await mode the action mirrors the run's conclusion onto this GHA step,

// Recipe: CDP acceptance tests — the `cdp-acceptance` Run
//
// The typed Run that ./ci.yml dispatches. Boots the app under test in a
// detached container, attaches Browser Rendering over the Chrome DevTools
// Protocol, runs the acceptance suite, and uploads screenshots + a trace as
// artifacts (see ./README.md — those can be attached to the PR).
//
// This recipe rides on two primitives — `workspace` (acquire + clone +
// cached install) and `bootApp` (detached run + wait-for-port) — so the file
// carries only the CDP-specific logic. See specs/03-dsl.md § Primitives.
//
// This is the shipped `cdp-acceptance` run, reproduced here so the recipe is
// self-contained. Spec: specs/02-runs.md § 4. DSL: specs/03-dsl.md.
