Release 4.209.0

The Quest guide on any page, and the current Live step in the Dock's agent view.

• The Quest guide for browser pages (#464). Pages can start the Quest guide from an opaque qstep link once the host resolves the step; it waits for late controls and checks the Events-backed completion read, and the shared navbar starts it from its own sign-in.
• The Dock's agent view shows the current Live step (#466) when the stream supplies one; older streams keep showing the task without a step line.
