Flags override the config file, which overrides the defaults. Every value can
also come from the file via ${env:VAR} — see https://miradb.dev/config/.
`mira mira` opens the terminal UI. With --data-dir it reads a block directory
in-process and needs no server running; with --addr it queries one over HTTP.
`mira tui` is the same thing, for anyone who guesses that first.
`mira update` replaces this binary with the latest GitHub release, using the
same installer as the curl one-liner at https://miradb.dev/install/.";
