node-facts: verbatim operator-verified files (fixture env without dotfile)

- Fix grep -qE calls to handle variables starting with '-' (add -- separator)
- Remove local declarations at top level by wrapping main body in main() function
- Replace bounded-worker scheduler with simpler temp file + wait -n pattern
- Fix per-node fan-out to capture function output instead of re-calling
- Add stub-curl integration tests that catch all three original issues
- Add fixture compose files for avalanche, op-node+beacon, geth testing
- Update test path-blacklist.txt to include entry starting with -

+### node-facts.sh — one JSON facts document per node
+
+`./node-facts.sh [node_path ...] [--pretty]` prints one JSON line per node (schema v1): running client
+image/tag and reported version, peer count + peer version histogram + `newer_than_us`, the protocol
+upgrade schedule the running config knows (chain config / rollup config / beacon spec / avalanche
+`info.upgrades`), chain signals (avalanche ACPs), head, and for OP-stack / beacon pairs a `consensus`
+block with the same fields for the consensus client. Every field is present; anything a client cannot
+provide is `null` with a `reason`. Read-only: compose files + `docker ps` + HTTP through the local
+traefik routes (`/<node>`, `/<node>/node`, `/<node>/eth`), parallel over nodes and calls, ~200 ms per
+host. Exit 2 with one error line if `.env`/`COMPOSE_FILE` is unreadable. Consumers: JobServer verb
+`node-facts`, controller `node-facts-collect` (CouchDB `node_facts:*`), Checkmk `node_facts_check.py`.
+Self-test (no network, no docker): `./test-node-facts.sh` runs the real main body against
+`node-facts-test/` fixtures via `NODE_FACTS_FIXTURES`.
