NCBI Fetch Accessions

Convert GenBank UIDs to accession numbers (U00096, NC_045512, etc.). Takes UIDs from NCBI_search_nucleotide and returns actual accession numbers that can be used with database tools. Returns both EMBL/GenBank accessions (U*, M*, AJ*) that work with ENA Browser tools, and RefSeq accessions (NC_*, NM_*) for NCBI tools. Use this as second step after NCBI_search_nucleotide to get usable accession numbers.
