The remote/headless session bridge now tracks a worker epoch alongside the existing worker bearer token, and reworked its teardown telemetry.

What

  • The remote session-bridge teardown path now assembles its preflush-hold and archive-status telemetry via helper functions, and exposes a new getWorkerEpoch accessor on the bridge host interface (alongside the existing getWorkerBearerToken) when a worker bearer token is available.
  • The headless/print-mode bridge mount setup now also passes a getWorkerEpoch accessor through to the same mount configuration.

Why This lets the bridge track which "epoch" (generation/instance) of a worker it's dealing with, which is internal plumbing that supports more accurate teardown and credential handling for remote/headless bridge sessions.
