Purpose
Linked issue: #361
Move the Lumina plugin from
src/paimon/global_index/luminatosrc/paimon/indexer/luminaand separate the Global Index adapter from the Lumina-specific reusable components.This change extracts the shared dataset, index accumulator, option parsing, tag conversion, and search lifecycle code.
LuminaIndexSearcherowns the opened native searcher and its extensions, performs vector-search dispatch, and closes the native searcher through RAII. The existing Lumina Global Index behavior remains unchanged.This PR does not add a Lumina File Index implementation or change the Paimon File Index and Global Index framework APIs.
