…ommon case (#65029) * Add fast-path heartbeat UPDATE to avoid row lock in the common case The ti_heartbeat endpoint now attempts a single guarded UPDATE (matching id, state, hostname, and pid) before falling back to the existing SELECT FOR UPDATE path. When the task is still running on the expected host this returns immediately, eliminating the row lock and a round trip for the vast majority of heartbeat calls. * fixup!

The ti_heartbeat endpoint now attempts a single guarded UPDATE
(matching id, state, hostname, and pid) before falling back to the
existing SELECT FOR UPDATE path. When the task is still running on
the expected host this returns immediately, eliminating the row lock
and a round trip for the vast majority of heartbeat calls.
