Memory exhaustion (DoS) via unbounded file read in `EncodingDiscovery.detect_encoding()`

`EncodingDiscovery.detect_encoding()` in `translation_finder/discovery/base.py` passes the raw file handle to `charset_normalizer.from_fp()`, which internally does `from_bytes(fp.read())` — the **entire file is loaded into memory**, with no size cap. Every other sniffing path in this codebase is …
