bsdr_micrelay — router-side owner-mic relay for bsdrX.

Pick the binary for your router's CPU and copy it there:
  bsdr_micrelay-arm64    64-bit ARM (most modern routers, RPi)
  bsdr_micrelay-armv7    32-bit ARM
  bsdr_micrelay-mipsel   little-endian MIPS (many OpenWRT routers)
  bsdr_micrelay-mips     big-endian MIPS
  bsdr_micrelay-amd64    64-bit x86
  bsdr_micrelay-x86      32-bit x86
Each is fully static (no libpcap/glibc needed on the router).

Auto mode (recommended) — zero config, serves every paired headset/agent in parallel:
  router:  ./bsdr_micrelay-<arch> --iface br-lan
  PC:      bsdr_agent --sniff-remote 45099   (or just enable the relay owner-mic method in the web panel)
The relay beacons; each PC finds it and registers for the headset it is paired with. The relay only
forwards a headset's mic to the agent it observed paired with it (bind-to-owner), so nobody can
siphon someone else's owner voice.

Static single flow (no discovery/auth), if you prefer to pin one headset:
  router:  ./bsdr_micrelay-<arch> --iface br-lan --quest <headset-ip> --to <pc-ip>:45099
(OpenWRT users: an .ipk recipe is in openwrt/bsdr-micrelay/.)
