chore(apm): regenerate content mirrors

Output of scripts/sync-plugin-content.sh --all against this round's .apm/
source edits. No file here is hand-edited.

Carries the agent-author and agent-audit documentation changes into the flat
mirrors. No compiled manifest changed: nothing in this round touched apm.yml,
so apm pack and sync-marketplace-mirror.sh both produced byte-identical output.
