imccyu ecdaf0dc24 test(web): connect a Workspace in the e2e boot path and refresh goldens
The startup-selection flow leaves a fresh world (no Workspace) in the
locked view state, so every e2e scenario that types into the composer
now connects one first via the shared connectFreshWorkspace helper
(hero picker create-by-name dialog; the default 'workspace' name keeps
the session-header cwd assertions intact).

Golden refreshes carry the current composer chrome: the plan/model
control seats are empty until their owning plugins register (the seats
shipped without occupants on this branch), the sidebar shows the
connected workspace group pre-send, and the bash details material
renders Input/code/Output as separate nodes. The cancel scenario polls
the frozen-partial swap instead of counting synchronously — the abort
frame reaches the browser over SSE after the host settles.

// Web e2e scenarios: live-turn interactions — cancellation, error surfacing,
// and transient-retry recovery, all through the real composition and wire.
// The model seam is dsh-llm-replay with override sidecars: `hang` (+ a
// readyFile marker) makes mid-stream cancel deterministic by construction,
// `throw` entries express provider failures by stable code, and `{ patches }`
// augmentation injects a transient throw before the recorded success so
// llm-retry's recovery is proven end-to-end in the browser. Sidecar CONTENT
// is authored here (single-sourced against the fixture via deriveReplayScript
// — no committed copy of recorded chunks); the file is a per-run artifact in
// the temp workspace. One recorded base fixture serves all three scenarios.
