Consolidates the standalone docker-compose.firehose.yaml into the main compose file as an opt-in `substreams-endpoint` profile, enabling a fully self-hosted EVM indexing stack without a StreamingFast/Pinax hosted endpoint. Changes: - Add `substreams-endpoint` profile: single-container Firehose stack (reader-node-stdin, merger, relayer, firehose, tier1, tier2) backed by any EVM JSON-RPC endpoint via `fireeth tools poller generic-evm` - Auto-resume on restart: poller starts from the highest stored one-block file, avoiding re-fetching already-fetched blocks - Add `observability` profile for lgtm/promtail (opt-in, was always-on) - Fix tycho-indexer healthcheck: use bash /dev/tcp instead of curl (curl is not present in the image) - Fix OTLP default: empty string disables exporter when lgtm is not running - Make SUBSTREAMS_ENDPOINT, CHAINS, and RETENTION_HORIZON configurable via env vars; remove hardcoded Ethereum defaults from the command - Remove chain-specific extractors-tempo.yaml volume mount - Delete docker-compose.firehose.yaml (superseded by the profile) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
