feat: add dsh-bilingual-reader to tab plugin catalog

Registers dsh-bilingual-reader in the better-sidebar add-tab-plugin catalog:
native-PDF reading with LLM selection translation, isolated from the main
conversation. Adds the catalog entry plus pluginBilingualReaderDesc across
all 20 locale dictionaries (zh/en source + 18 mirrors).
