Adds a workflow_dispatch + daily-cron GitHub Action that GETs
https://api.comfy.org/nodes/imagemetahub-comfyui-save and appends an
append-only JSONL record (timestamp, downloads, github_stars, rating,
search_ranking, latest_version, status, plus delta vs the previous
record) to metrics/registry-history.jsonl, then commits it back.
- No external service, no secret, no paid dependency (stdlib urllib + git).
- permissions: contents: write only.
- Bot commit message includes [skip ci] so it cannot trigger other
push-triggered workflows (e.g. the registry publish workflow already
scoped to pyproject.toml changes only).
- Does not touch node runtime behavior.
