Subject: feat: add bash completion

Completes the flags, and directories for --archive-dir in both the
--opt value and --opt=value forms. --target offers only "me": real chat
handles would need a network round-trip inside a tab press, and
--list-chats already answers that question.

Installed by hand, nothing automates it. A new flag has to be added to
opts in the completion as well.
