SessionReplayer replays golden fixtures through DeterministicScenario;
add HBP group voice session, behavior tests, and dev CAPTURE scaffold.
Set pytest pythonpath so bare `pytest` finds tests.* imports.
Move Talker Alias / embedded LC and BRIDGES table lifecycle into
application/bridge/; BridgeUseCases remains the public facade with
dmrd_received and unit/private paths only.
Introduce RuntimeContextHolder with ConfigProxy so main wiring keeps a stable
config view while SIGHUP reload builds a deep copy, applies reload_server_config,
then swaps the pointer only on success.
