Subject: [PATCH] test(web): file save session browser test no longer hangs on
 the discovery poll

The hook's writable-access subscription mounted the real session atom, which
boots the connection runtime and its endless platform discovery poll. When that
poll scheduled its timers after the test installed fake timers (a slow CI
runner), vi.runAllTimersAsync chased it until the 15s test timeout. Stub the
session atom with an inert one so the test owns every timer it drains.
