MediaCmd::Drain flips a draining flag that rejects new Registers with
the "draining" contract string (routes already map this to 503, Task
3) while existing sessions keep ticking; the reply fires once the
session map empties, checked right after the eviction sweep so a tick
that closes the last session completes the drain in the same
iteration. MediaStats.draining now reports the real flag instead of
the Task 3 placeholder.
config::drain_deadline parses RUTSTER_DRAIN_DEADLINE_SECS, defaulting
to 0 (today's instant dev-loop shutdown). main.rs restructures the
serve/shutdown tail into two phases: on SIGTERM, send Drain while axum
keeps serving (in-flight calls still need DELETE/offer, and Task 5's
readyz will flip so the LB pulls the node), wait for drain-complete or
the deadline, THEN quiesce HTTP and call media_thread.shutdown() for
the hard stop. Calls are non-migratable by design, so drain-then-
terminate is the only graceful scale-in shape.
