" summary

Compiles an existing C QC tool (ctk) to WebAssembly with Emscripten, mounts uploaded FASTQ files into the virtual filesystem, and runs the analysis inside a WebWorker so the UI stays responsive. Out-of-the-box result is about 9x speedup, removing unneeded prints yields ~13x and merging duplicate functions reaches up to 20x speedup; fastq.bio is front-end only and these changes noticeably make the interactive plots update much faster.
