v0.9.0b1

---

• Fix: Universal Scanner DTC registers showing as zero on fresh TCP connection:
  When using the export_register_dump scanner, the DTC identification registers (holding
  30000 and holding 43) frequently returned 0 even though reading them individually via
  read_register always worked. Root cause: the scanner opens a new raw TCP connection, which
  displaces the coordinator's existing session. Until the inverter settles, the first reads
  return 0 with no Modbus error. Fixed by adding a 500 ms warmup delay after connecting, plus
  a single retry (with delay) for each DTC register if it reads back as zero.
