Two root causes behind HackRF showing as unavailable when tools are installed: 1. get_tool_path() didn't search /usr/local/bin on Linux. HackRF tools built from source (as in the Dockerfile) land there, but the path wasn't checked when sudo/service environments have a restricted PATH. 2. check_hackrf() only tested hackrf_transfer, but the health check tests hackrf_info — both come from the same apt package but a user could have one visible and not the other. Now either binary confirms the tools are present. hackrf_transfer is still required for actual RX/TX operations. Fixes #212 Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
