feat(pyproject): pin decnet-behave-{core,shell} >=0.1.0,<0.2

Lock the BEHAVE library versions per BEHAVE-INTEGRATION.md
§Versioning. The profiler worker (Phase 4 wiring) imports
`Observation`/`Window` from `decnet_behave_core.spec.envelope` and
`event_topic_for`/`to_event_payload` from
`decnet_behave_shell.spec.event_adapter`; without the pin a broken
wheel or missing install would only show up on first publish.

Four-test smoke pins the public surface: envelope construction,
registry import non-empty, event-adapter topic shape, and the
adapter's id/ts/v exclusion contract.
