OTEL_PYTHON_HTTPX_EXCLUDED_URLSafter each test.
init_httpx_instrumentor()adds a default value when the variable is absent. The first and third tests leave that value in the process environment. The exclusion test deletes any prior value instead of restoring it. This can change later tests or externally supplied test configuration.Use a fixture that snapshots the original value and restores it during teardown. Also uninstrument in that fixture.

Summary
Adds
Instruments.HTTPXsupport to the traceloop SDK for #2283, building on the work started in #4070 with tests, dependency declarations, lockfile updates, and URL-exclusion wiring.What changed
Instruments.HTTPXenum member, dispatch branch ininit_instrumentations, andinit_httpx_instrumentor(mirrors the existing requests/urllib3 instrumentors).opentelemetry-instrumentation-httpxandhttpxas SDK dependencies;uv.lockupdated accordingly.tests/test_httpx_instrumentation.py(no network): init wiring, span capture with attributes, and excluded-URL behavior using a local server.Design decisions (please review)
Traceloop.init()(noinstrumentsargument) resolves toset(Instruments)ininit_instrumentations. Adding HTTPX to that default caused 9 to 12 existing tests to fail (test_workflows.py,test_association_properties.py,test_prompt_management.py,test_privacy_no_prompts.py,test_span_postprocess_callback) because those tests assert exact span lists, and httpx-based libraries (openai, langchain-openai) emit HTTP client spans even when the call is replayed from a cassette. If you prefer REQUESTS-parity default-on behavior, the one-line change is to remove- {Instruments.HTTPX}from the default, at the cost of updating those exact-span tests.
