Release v0.63: Lattice-based (post-quantum) cryptography

This release adds a fourth group abstraction layer for lattice-based
cryptography, backed by the NTL C++ library.

New Lattice-Based Crypto Module:
- C++ extension (charm.core.math.lattice) with polynomial ring arithmetic
  in R_q = Z_q[X]/(X^n+1), discrete Gaussian sampling, and vector/matrix ops
- Python wrapper (LatticeGroup) with API matching PairingGroup/ECGroup
- Named parameter sets: RLWE, KYBER-512/768/1024, DILITHIUM-2/3/5

New Schemes:
- RLWE-PKE (LPR): Ring-LWE public key encryption
- Kyber KEM: Simplified ML-KEM (FIPS 203) key encapsulation
- Dilithium Sig: Simplified ML-DSA (FIPS 204) digital signatures
- Lattice IBE: Simplified ABB10 identity-based encryption

Bug Fixes:
- Fix Python 3.13+ enum name-mangling crash (EnumValue.__value)
- Fix unconfigured pairing_lib handling on Python 3.13+

Build:
- Opt-in via LAT_MOD=yes (requires NTL: brew install ntl / apt install libntl-dev)
- NTL auto-detection in configure.sh and setup.py
- 44 new tests, full CI coverage

Release v0.62: Threshold ECDSA schemes

This release introduces production-ready threshold ECDSA implementations:

New Threshold ECDSA Schemes:
- GG18 (Gennaro-Goldfeder 2018)
- CGGMP21 (Canetti et al. 2021)
- DKLS23 (Doerner et al. 2023)

Applications include cryptocurrency wallets, multi-party custody,
and decentralized signing services.

Contributors:
- J. Ayo Akinyele (GG18, CGGMP21)
- Elton de Souza (DKLS23)
