Misleading error message when using shadowed process name in map

If you run:

process FOO { 
    script: 
    '''
    echo hi
    ''' 
}

workflow {
    def FOO = 1
    channel.of(FOO).map { v -> FOO(v) }
}

it raises the following error:

Error test.nf:10:34: Processes cannot be called from within a closure
│  10 |       channel.of(FOO).map { v -> FOO(v) }
╰     |  

However if you do

channel.of(FOO).map { v -> FOO }.view{ v -> "v is ${v}"}

You find that v is 1 and that the process is in fact shadowed by the local variable declaration, so it would seem that the error should really be that FOO is not callable?

Environment

• Nextflow version: 26.04.6

Start by running the supplied Nextflow script and comparing the process-call case with the shadowed-value case. Trace the closure invocation and name-resolution entry points to determine why the process-specific error is selected; done means the shadowed value produces an accurate non-callable error without changing the valid process behavior.
