rewrite generated CLI docs' passive voice to active

hive-forge and hivectl doc-comment strings for pr-create --label, diff
--full, list --label, ci-runs --branch, and several hivectl subcommand
options read as if things happened to themselves. Name the actor (hivectl,
hive-forge, or the CLI) instead, and regenerate the three docs/tools/*-cli.md
files from the rebuilt binaries.

swarmctl-cli.md needs no source change: its only passive hit is
clap-markdown's own generated boilerplate, out of scope here.
