feat: add full 6-step NGS pipeline + fix sequencing WinError 193

feat: add DNA sequence output across BLAST, UniProt, sequencing, primers, and SequenceRetrieval

fix: replace dead lambda reference FTP URL with NCBI E-utilities

fix: resolve 10 bugs in sequencing/docking pipelines

Fix pipeline stuck issue: synthetic FASTQ fallback and demo mode

Move minimap2 download to runtime (avoids build failures on HF cpu-basic)

Phase 3: Sequencing pipeline (FASTQ -> QC -> alignment -> variant calling -> report)
