Fixes HTTP 413 (Payload Too Large) errors on the /graph and /run_passes
routes when visualizing or optimizing large XLS IR packages.
- Client-side (ir_visualizer.js, ui.js): Compresses IR text using the
browser CompressionStream API ('gzip') and sends it as 'text_gzip' in
FormData with fallback to uncompressed text.
- Server-side (app.py): Extracts and decompresses IR text from multipart
FormData, raw bodies (Content-Encoding: gzip/deflate), or auto-detected
magic bytes. Compresses JSON responses with gzip when requested by the
client and avoids redundant Python JSON deserialization/serialization.
