Summary
Switches the indexer's blockchain provider from WebSocket subscriptions to periodic HTTP polling.
Previously the indexer backfilled over HTTP and then transitioned to live WebSocket streaming, which required a separate
WS_URLendpoint and theprovider-wsalloy feature, and reconnected on every dropped socket. It now syncs entirely over HTTP RPC, polling for new events on a fixed interval.Changes
blockchain/mod.rs: replacebackfill_and_stream_events(websocket) withpull_events(periodic HTTP polling)WS_URL/ws_rpc_urlconfig, theMissingWsUrlerror, and theprovider-wsalloy featureBLOCKCHAIN_POLL_INTERVAL_SECS(default1) to control the poll interval.env.example, README, and integration tests accordingly
