What does this PR do?
Flush pending feature flag evaluation and exposure EVP telemetry through the tracer's versioned internal contract after every invocation, including handler errors and failures in unrelated cleanup. Keep providers and their workers available for warm invocations.
DD_FEATURE_FLAG_FLUSH_TIMEOUT_MSdefaults to 500 ms. The wait is capped at remaining invocation time minus a 100 ms safety margin. Older tracers or unused OpenFeature safely skip the capability. Incomplete flushes produce debug diagnostics without replacing the handler's response or original exception.Motivation
Short invocations can finish before background telemetry flush intervals. Part 2 of FFL-3412, depending on dd-trace-py #21135.
Testing Guidelines
tests/integration/FEATURE_FLAG_FLUSH.md.Additional Notes
Draft pending tracer release coordination and a deployed ingestion test. AWS sandbox credential acquisition returned SSO 403; no deployed smoke test has been completed. Record the first supported published tracer, Lambda library and layer versions together before announcing support. The default layer build must include the tracer capability; this PR intentionally does not invent an unreleased dependency version.
Timeout stops waiting, not the underlying send; delivery remains best effort. This PR is submitted from a personal fork because upstream push access was denied.
