Remote sessions can answer liveness probes and resync after a dropped connection.

Anonymous. No account, no email.
What
The long-lived connection to remote sessions can now tell the server it accepts liveness probes, report the heartbeat interval it is using, and respond to a probe frame. After a dropped connection it runs a resync, and it will not accept a server-suggested heartbeat interval that outlives the current auth token.
Details
- Turned on by an
advertiseLivenessProbeSupportoption on the transport; nothing in this build was found to set it. - Probes are logged as
cli_sse_liveness_probe_received; unrecognised transient frame types logcli_sse_unexpected_ephemeral_type. - A heartbeat is forced immediately after reconnect, spaced for probes.
Evidence
cli_sse_liveness_probe_received
