The tmux session name "gt-deacon-boot" was causing HasSession("gt-deacon")
to return true due to tmux prefix matching behavior. This made the daemon
think the Deacon was running when only Boot was active, and caused commands
targeting "gt-deacon" to be sent to Boot session instead.

The fix renames Boot session from "gt-deacon-boot" to "gt-boot", which
has no prefix overlap with "gt-deacon".

Fixes: gt-sgzsb
