BrianHotoppandClaude Opus 4.8 c78d6af748 [2.x] fix: Complete server teardown before logging so reboot works from sbtn (#9497)
Running reboot in the sbt shell dropped to the OS shell instead of rebooting.
The break was in teardown: Server.shutdown opened with
log.info, and during a client-initiated reboot the terminal in scope is that
client's already-closed virtual terminal, so the log write throws
ClosedChannelException through the terminal proxy. That aborted teardown
before the portfile was deleted and the server socket closed, and the
exception was swallowed by the shutdown hook (whose own error print goes to
the same dead terminal).

Server.shutdown now completes its state cleanup (portfile, tokenfile, running
flag, server socket) before logging, and CommandExchange.shutdown wraps each
channel shutdown and the server shutdown individually so one failing step
cannot skip the rest.

Fixes #9095
