fix: reap only our own jobs, and say why a vale probe missed

batch_run ended with a bare wait, which blocks on every background job the
calling shell has, not the ones it started. Harmless for all three current
callers, but a future caller that backgrounds anything of its own would have
batch_run block on it or consume its status. It now records each $! and reaps
exactly those PIDs.

The `wait "$pid" || true` there is load-bearing: unlike a bare wait, wait <pid>
returns the job's status, so without it a single failing job would abort the
set -e caller at the call site -- before run-tests.sh or sync-plugin-content.sh
could read their .status files and print a summary. Status semantics stay in
those files, exactly as before.

check-vale-style-sync.sh's glob probe discarded vale's exit code and output and
decided purely on a grep, so a failed exec, an OOM-killed vale or a full TMPDIR
was indistinguishable from a real glob defect -- both printed "its glob sections
do not cover a path" with no evidence. A flake seen once in this probe could not
be diagnosed afterwards for that reason. The probe now attaches vale's rc and
output: a genuine glob defect reads "vale exited 0 ... in 0 files", a killed vale
reads "vale exited 137; output: <empty>".

That flake was investigated and not reproduced -- 1680 probes across three
contention setups including an offline namespace, all clean -- so nothing is
changed speculatively. The misattribution is worth recording: it was reported
against tests/test-vale-wrap.sh, which never invokes this script; the assertion
belongs to check-vale-style-sync.sh and reaches a log through a different suite.

Also drops the last stale field roster from agent-author's scaffolder. Its
next-steps hint enumerated "(name, description, model, body only)" -- omitting
disallowedTools, and never accurate anyway, since the template marks only
description and the body FILL IN. Its --help carried the inverted form, already
missing six forbidden fields. Both now state the shape rule and point at
field-inventory.md, and a bats case enforces all-or-nothing: name every
allowlisted field or name none, since a partial roster is the shape that goes
stale silently.

@@ -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.
