/** SDK-owned platform module. This implementation is maintained in goodvibes-sdk. */
/**
 * Code-index SQL layer, schema plus every direct table operation for
 * CodeIndexStore's bun:sqlite database (Stage A, see CHANGELOG 0.38.0; extracted from
 * code-index-store.ts to keep that file within the 800-line source discipline).
 *
 * Three tables:
 *  - `code_chunks`    chunk metadata (path/lang/symbol/kind/lines/hashes)
 *  - `code_vectors`   vec0 virtual table keyed by rowid
 *  - `code_index_meta` key/value build provenance, currently the embedding
 *    provider id the index was last fully built with, so search() can refuse
 *    to compare query vectors from a different provider's space against the
 *    stored vectors (see CodeIndexStore.getProviderMismatch).
 *
 * Every function takes the Database handle explicitly, this module holds no
 * state and never opens/closes connections; CodeIndexStore owns the lifecycle.
