Introduces a withSpan helper that wraps async functions in OpenTelemetry spans with enter/exit events, error recording, and automatic span lifecycle management. Foundation for function-level instrumentation.
Wraps all auth pipeline functions with OpenTelemetry spans: P_CreateChallenge, P_CreateChallengeDB, P_CreateChallengeMemory, P_VerifyChallenge, P_CompareChallenge, P_GenerateChallengeJWT, and related store/update functions.
Wraps all service functions with withSpan using Class.method naming: Bundle.validateSession, Bundle.parseOperations, Bundle.persistCreate/Spend, Executor.buildTransactionFromSlot, Executor.submitTransactionToNetwork, Executor.ensureOpexUtxosAvailable, Executor.handleExecutionFailure, Verifier.verifyTransactionOnNetwork, Mempool.reAddBundles, and P_AddOperationsBundle, P_GetBundle, P_ListBundles process pipelines.
….provider-b.toml Adds commented-out OTEL configuration section to .env.example, adds OTEL environment variables to docker-compose provider service, and removes unused fly.provider-b.toml deployment config.
