Task 09: E2E coverage

Spec: §"Notes for implementation" (injectable probe seam), AC-73.

Injectable probe seam

AC-62, AC-68, AC-73 need the probe's answer to change mid-test without a real 12-minute wait. Add a test-only override path (mirroring how the mock agent / KANDEV_E2E_MOCK profile already injects scripted behaviour elsewhere) that lets an E2E spec drive BackgroundProbe.Probe through a scripted sequence for a given session. Keep this entirely inside the e2e/mock profile gate — it must not be reachable in prod.

Scenarios

• AC-73: three consecutive live samples then settled, with a self-resume on the transition — assert the background test id renders at every live sample and neither waiting-for-input nor turn-finished renders while parked (board and sidebar).
• AC-62: live → settled transition clears the affordance and the task row updates without a page reload (WS-driven).
• AC-68: agent self-resumes (session leaves WAITING_FOR_INPUT) while the probe is still live — affordance clears immediately.
• AC-51/AC-34: session switcher and sidebar precedence — parked session with and without a concurrent pending clarification/permission.

Real process-tree ACs (AC-70/70a/71/72/80) are covered by task-03's Go tests, not E2E — no real 12-minute-shell E2E scenario is required by the spec.

Follow the repo's e2e conventions (apps/web/e2e/README.md); this feature does not need the containers project (no Docker/SSH executor dependency).
