After using migration assistant (over Thunderbolt) – from a MacBook Pro 5,4 to a MacBook Pro 11,4 – Terminal shows the old computer name at the prompt. This happens despite updating the computer name in System Preferences' Pane for Sharing. I've scoured the Console and the System Report.

The bash shell will do a reverse DNS lookup using your current IP address. If a DNS server responds with a name, then bash will display that as the computer name.
You could try
sudo scutil --set HostName "name-of-host"
You could reboot your home router, or in some way get whatever is acting as your DNS server to forget what it knows.

In any of the "dot" files in your home directory (e.g. .bashrc, .bash_login, .bash_profile, .profile), and assuming you are using Bash as your default shell — are you manually setting your old hostname anywhere in these files?
Is your /etc/resolv.conf file showing your expected DNS server entry?
If you do nothing, and use VPN, your hostname will be automatically set to the DNS server's assigned hostname, and will bypass the Sharing panel entry. The /etc/resolv.conf will automatically be updated with the VPN DNS server address.
And it continues despite scouring the Network pane's settings for DHCP Client IDs.
