Walkthrough

The PR extends the API comparison testing infrastructure to support lotus-gateway testing by updating environment variables, adding new Docker services for gateway-based API comparisons, and introducing a filter list for unsupported/broken gateway methods.

Changes

Cohort / File(s)	Summary
Environment Configuration scripts/tests/api_compare/.env	Updated LOTUS_IMAGE from v1.34.4-rc1-calibnet to v1.34.4-calibnet; added FOREST_VIA_GATEWAY_RPC_PORT=4567.
Docker Orchestration scripts/tests/api_compare/docker-compose.yml	Added three new services: forest-via-gateway (runs lotus-gateway with health checks), api-compare-gateway (compares gateway APIs with multi-service dependencies), and forest-shutdown (cleanup service). Removed F3 certificate wait loop; restructured service dependencies and coordination.
Gateway Filtering scripts/tests/api_compare/filter-list-gateway	New static file defining unsupported and broken Filecoin API methods for lotus-gateway (67 lines across two categorized sections).

In `@scripts/tests/api_compare/.env`:
- Around line 2-10: The .env file has dotenv-linter ordering warnings for keys
such as FOREST_IMAGE, LOTUS_IMAGE, FIL_PROOFS_PARAMETER_CACHE, LOTUS_RPC_PORT,
FOREST_RPC_PORT, FOREST_OFFLINE_RPC_PORT, FOREST_VIA_GATEWAY_RPC_PORT,
FOREST_HEALTHZ_RPC_PORT and CHAIN; fix by reordering the entries into the
linter-expected order (e.g., alphabetically by key) so keys like CHAIN,
FIL_PROOFS_PARAMETER_CACHE, FOREST_HEALTHZ_RPC_PORT, FOREST_IMAGE,
FOREST_OFFLINE_RPC_PORT, FOREST_RPC_PORT, FOREST_VIA_GATEWAY_RPC_PORT,
LOTUS_IMAGE, LOTUS_RPC_PORT appear in sorted order to remove the dotenv-linter
noise. Ensure no values or spacing are changed beyond reordering.

In `@scripts/tests/api_compare/docker-compose.yml`:
- Around line 314-338: The docker-compose teardown service forest-shutdown never
runs on test failures because api-compare doesn't reach
service_completed_successfully; update the test orchestration to guarantee
cleanup by either adding the --abort-on-container-exit flag to the docker
compose invocation in setup.sh so compose will shut down all containers when any
exits, or add a process-level fallback trap in api_compare.sh (e.g., trap on
EXIT) that invokes docker compose down to ensure the forest container is
stopped; pick one approach and implement it so forest-shutdown is not relied on
as the sole cleanup path.
