What
An idle remote session can now beat far less often when the server asks it to. The upper limit on a server-advised heartbeat interval was a flat 900000 ms; it is now effectively unbounded, still capped by the session token's lifetime.
Details
Only applies when the caller advertises heartbeat probe support, which defaults to off; without it the ceiling stays 300000 ms.
The new ceiling is computed as the maximum 32-bit integer divided by one plus the jitter fraction.
