Drafts CHANGELOG_PENDING.md entries from Conventional Commit subjects on
every push to main -- feat/fix/refactor/perf/security bucketed into
Added/Fixed/Changed, chore/ci/test/docs/style/merge skipped, anything
mentioning internal infra hostnames dropped. No LLM call, no network
access. Never touches CHANGELOG.md -- still needs a human to fold an
entry in. Rolled out fleet-wide from the PeerCortex pilot (2026-07-18).
