Updates hashlib module and tests to Python 3.14.2 compatibility.

Changes

  • Updated Lib/hashlib.py and Lib/test/test_hashlib.py from CPython v3.14.2 using update_lib tooling, preserving 10 RustPython TODO markers

  • Created _sha2 module (crates/stdlib/src/sha2.rs): Python 3.14 consolidated _sha256 and _sha512 into a single _sha2 module providing all SHA-2 family functions (sha224, sha256, sha384, sha512)

  • Added openssl_md_meth_names attribute to _hashlib module: Returns frozenset of available hash algorithms, required by Python 3.14's hashlib.py to populate algorithms_available

Test Status

82 tests run: 8 expected failures (matching TODO markers), 2 TODO tests skipped (urlfetch disabled), 15 platform/resource skips.
