mute fcd172f341 fix: premature socket teardown on CLOSE + duplicate CLOSE echo ...

Two bugs when upstream closes:

1. Data loss: gatuna received CLOSE from gatunad and immediately
   RST'd the socket to curl while the drain pump still had queued
   payloads in _deliverChannel. Fix: OnRemoteClose() completes the
   channel writer and cancels the read pump, but lets the drain pump
   finish naturally. Drain pump no longer takes _cts.Token — it stops
   on channel completion and closes the socket gracefully (FIN, OS
   flushes in background).

2. Duplicate CLOSE: gatuna echoed CLOSE back to gatunad (server
   already knows — it initiated). SendClose() now guarded by
   _closeSent flag. OnRemoteClose() never sends CLOSE at all.

Server-side: remove session from store before sending CLOSE so the
retransmit timer stops before CLOSE is queued. Only log CLOSE if
the session actually existed (dedup).
