docs(kyberforge): document source_keys as 4th apm-agent-allowlist field

field-inventory.md's apm-agent-allowlist and validate.sh's runtime
check already included source_keys as a 4th allowed field, and the
apm-agent.md template already instructed authors to add it for
provenance tracking — but SKILL.md (x2), README.md, ADR-0016, and
deployment-modes.md still described the allowlist as name/description/
model, "nothing else". The template itself even contradicted its own
source_keys guidance with a header claiming "ONLY the three fields
below — full stop" directly above it.

Updates all six locations to document source_keys as the intentional
4th field, resolving the contradiction.

 `vale-wrap.sh` ships inside this skill's own `scripts/` — resolve it relative to this skill's directory the same way `scripts/validate.sh` is resolved above, so the invocation works whether this skill is running from this repo or from an installed plugin cache. Pass no `--config`: handed none, the wrapper loads its own sibling `assets/vale/.vale.ini`, located from the script's path rather than from the cwd. Adding an explicit relative `--config` breaks exactly the case the self-location covers — a resolved script path plus an unresolved config path yields `E100 Runtime error ... does not exist`, exit 2, which the fallback below then misreads as "vale unavailable". At project/user scope, run it against both files of the pair (not just the one passed in); at plugin/APM scope, run it against the single file. `Kyberforge` applies to all of these files via the `**/agents/*.md` glob; `KyberforgeCopilot` applies to any `*.agent.md` file — including the plugin/APM-scope file, which already has that extension — via the `**/*.agent.md` glob, since its one rule (`Use proactively`) flags CC-specific phrasing that's meaningless in a vendor-neutral or Copilot description. Every Vale alert is a `FAIL` — all rules are graded `error` — so report each one in the `### Description` / `### Body` dimensions citing its rule ID (e.g. `KyberforgeCopilot.ProactivePhrase`). Skip and fall back to Step 2 judgment if the `vale` binary is unavailable. If Vale reports `0 files` scanned, treat the pass as NOT RUN — not as clean — and fall back to full Step 2 judgment for the dimensions it would have covered.
 
 `validate-provenance.sh` operates at plugin/APM scope only — it walks up from the agent file's directory the same way `validate.sh` does (nearest ancestor `apm.yml` with a top-level `type:` field; skip a `type:`-less marketplace-only `apm.yml`; stop at `.git` or the filesystem root) and exits 0 silently if that walk doesn't land on a package root, or when no provenance data exists. When it does apply, it validates the chain between the single file's own `source_keys` and the package-scoped `sources.md` (package root — see ADR-0010). Note FAILs from this script for the `### Provenance` dimension — surface them verbatim with Why and Fix.
