* intitial refactor: - Add Context-based graceful shutdown and drain phase for enqueued requests - Use buffered channels vs. mutex for concurrency mgmt. - Use atomic.Pointer vs. locks for FF mgmt - Use Callback ifc vs. lossy internal tracking for unit test result validation - Add new APIs mirroring current that accept caller's Context to control operation timeouts * expose batch submission timeout with default equiv to old hardcoded timeout * restructure event submission and batching pipeline * overhaul tests; implement new stress tests and address coverage gaps * parallelize tests where safe to do so (3x CI time savings!) * introduce faster pure Go JSON seralization library * more refactors: unit tests & benchmarks * DRY up shutdown req drain and prepareForSend serializer * use go-json in CLI utils too; remove redundant helpers * move error type to proper pkg * DRY up loop() and fix deadlock in old test case * normalize CI and Makefile test and benchmark target behavviors * more realistic feature flags benchmark * replace leaky time.After pattern with idiomatic safer Timers * internal queue size minimums decoupled from batch and worker configs * remove dead comments * fix test bug * update default http.Transport cfg to avoid conn pool as bottleneck; update batch enqueue limiting strategy and tests/benches * adjust stress test defaults to match prod * update flaky tests and rm stale file * make graceful shutdown timeout opt-in for now * fix tests that reverted to hold helper utils during rebase * fix flaky test due to overhead from -race detector now default in test flags * add more graceful shutdown test cases
