feat: update Vm.sol with new cheatcodes (#819)

## Summary
Update `Vm.sol` with all new cheatcodes from foundry.

## New cheatcodes
- `createEd25519Key(bytes32 salt)` — generate Ed25519 key pair from
deterministic salt
- `publicKeyEd25519(bytes32 privateKey)` — derive Ed25519 public key
- `signEd25519(bytes namespace, bytes message, bytes32 privateKey)` —
sign with namespace using Ed25519
- `verifyEd25519(bytes signature, bytes namespace, bytes message,
bytes32 publicKey)` — verify Ed25519 signature
- `executeTransaction(bytes rawTx)` — execute RLP-encoded signed tx with
full EVM semantics (like `--isolate` mode)

## Generation
Regenerated via `scripts/vm.py --from cheatcodes.json` using foundry's
latest `cheatcodes.json`.
