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.
