BLD14: a run's input is asked of the verb the asker's ask names

The Go build module asks the input verb in the ask (the checker's, the
indexer's mesh-catalog input or the assigner's mesh-wants input) and its
manifest invokes the two seats' verbs. The bus refuses the other accounts
(grants of the contract's callers). The step key keeps the contract's form
<node>.<id>: no asker part is named there (question to the lead).

Builds: design 47 G §125, §206, §338, §354
