Add dynamic instrumentation and exception replay to startup logging (#3667)

p-datadog · p-ddsign · claude · web-flow · commit f4ce0bf9d70c · 2026-03-17T23:17:31.000+01:00
The startup configuration JSON now includes the status of
DD_DYNAMIC_INSTRUMENTATION_ENABLED and DD_EXCEPTION_REPLAY_ENABLED,
making it easier to verify these features are configured correctly
when the tracer starts up.

Updated the corresponding tests to expect these new fields.
