docs(0145): cerrar issue + actualizar README

Mueve 0145 a completed/ tras validar smoke real del binario:

echo '<initialize>+<notif/initialized>+<tools/list>' | bin/devicemesh-mcp
  --device-agent http://127.0.0.1:9999 --mode user
  --tools-allowed "exec,fs.read"

devuelve dos frames JSON-RPC esperados:
1. initialize result con serverInfo.name=devicemesh + capabilities.tools.
2. tools/list result con exec + fs.read, inputSchema completo incluyendo
   required fields (argv, path).

Suite de tests con -tags goolm -count=1 pasa sin errores.
