docs, prompts, hive-forge: stop handing readers the renamed verbs

docs/tools/forge.md already listed the nine renamed verbs as removed, then
used them ~30 more times in pasteable blocks. Sweeps every occurrence a
reader would type, including three runtime messages that told the user to
run a verb the same binary rejects.

The renamed-verb list itself keeps the old names; it is what documents them.
