Gate startup logs behind PI_DEBUG + skip GGUF-shard phantom entries

- All [ai-server] / [markdown-body-color] / [mechanicus-thinking-label]
  console.log calls now fire only when PI_DEBUG is set. Default boot is
  clean.
- ai-server's discoverModels now filters out ids matching
  /-\d+-of-\d+$/ — llama.cpp's --models-autoload registers every GGUF
  shard as its own id, duplicating the preset's consolidated model.
  These shard-named phantoms are no longer surfaced to pi.
