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 agent-author's scaffolder and its contract doc into the flat mirror.
No compiled manifest changed: nothing in this round touched apm.yml, so apm
pack and sync-marketplace-mirror.sh both produced byte-identical output.

@@ -15,6 +15,7 @@ All scripts in this skill must follow these rules:
 - **Idempotent** — "create if not exists" per file. The scaffold script skips any file that already exists; agents may safely re-run it.
 - **Meaningful exit codes** — `0` success, `1` invalid arguments or precondition failure. Document in `--help`.
 - **Self-contained** — no external package installs at runtime. The script uses only bash builtins and POSIX tools (`sed`, `mkdir`, `cat`).
+- **No restated field rosters** — no script output, in `--help` or in next-steps guidance, enumerates permitted, forbidden, or required frontmatter fields. Point at the `apm-agent-allowlist` section of `agent-audit`'s `references/field-inventory.md`, which `agent-audit`'s `validate.sh` reads from there as data. A roster copied into script output goes stale one step further out than the list itself: the next-steps hint `(name, description, model, body only)` kept printing after ADR-0016's 2026-08-14 amendment added `disallowedTools` to the permitted set. `tests/new-agent.bats` enforces this for the plugin/APM branch — naming some allowlisted fields but not all is a failure.
