Subject: [PATCH] perf(maestro): disable Nagle on the daemon listener
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Keystrokes and PTY echo are tiny frames. With Nagle on, each can sit up to
40ms waiting for an ACK before the kernel sends it — invisible over
loopback, plainly felt from another device on the LAN.
