hive-forge, hivectl, swarmctl: fix clap help passive voice, regen docs

Rewrites every write-good.Passive hit in the hive-forge clap help text
into terse, imperative, active voice (meaning unchanged) and drops
clap-markdown's own fixed footer ('This document was generated
automatically by...') via MarkdownOptions::show_footer(false), since
that string isn't ours to reword and vale flagged it too.

docs/tools/{hivectl,swarmctl,forge}-cli.md are generated from each
crate's clap tree (see hive-forge/src/main.rs's MarkdownDocs verb) —
regenerated here from the fixed source, not hand-edited.
