Replaces `io.StringIO(file.read().decode())` with `io.TextIOWrapper(file)` for `mgf` and `mztab` file loading. This avoids loading the entire file into memory as bytes and then again as a string, significantly reducing memory footprint for large spectral files.

💡 What: Replaced the file loading mechanism in
app.py. Instead of reading the full uploaded file content into memory, decoding it, and creating aStringIObuffer, we now useio.TextIOWrapperto wrap the underlying file stream.🎯 Why: The previous approach required approximately 2x-3x the file size in memory (bytes + decoded string + buffer overhead). For large proteomics files (MGFs can be GBs), this causes significant memory pressure or OOM errors.
TextIOWrapperprocesses the stream on-the-fly with minimal buffering.📊 Impact:
🔬 Measurement:
