- Fix bn256/gnark imports to use crypto/bitutil instead of standalone bitutil
- Remove unused secp256k1 import from crypto.go
- Fix mlkem test files to use correct API (GenerateKeyPair returns pub,priv,err)
- Fix mlkem constant names (MLKEM512SharedKeySize not SharedSecretSize)
- Restore crypto/common types as standalone (not aliases to geth/common)
- Update crypto.go and keccak.go to use crypto/common instead of geth/common
- Fix secp256k1 fuzz tests to use correct DecompressPubkey/CompressPubkey API
- Remove stale test files and go.work files
crypto package is now fully independent of geth (geth -> crypto, not reverse)
