genesis: ValidatorManager schema accepts a validator public key of any length; the chain requires 32 bytes

[JspIIV]

Summary

scripts/genesis/ValidatorManager.ts types a validator publicKey as schemaHex — any 0x plus an even number of hex digits — while the chain only accepts 32-byte keys:

// contracts/src/validator-manager/ValidatorRegistry.sol
require(publicKey.length == ED25519_PUBLIC_KEY_LENGTH, InvalidPublicKeyFormat());

The 32-byte rule exists in the genesis tooling only as a throw new Error('Public key must be 32 bytes') inside buildValidatorManagerGenesisAllocs. genesis.ts parses the whole config with schemaGenesisConfig.parse first (line 161) and builds later (line 188), so a 31-byte key passes validation, passes the public-key uniqueness check, and only fails afterwards with an error that names no path.

Steps to reproduce

import { schemaValidatorManager } from './scripts/genesis/ValidatorManager'
schemaValidatorManager.safeParse({ ...validConfig, validators: [{ publicKey: `0x${'11'.repeat(31)}`, votingPower: 20n, controllers: [...] }] })
// => success: true   (expected: false, path validators.0.publicKey)

Expected behavior

The schema rejects any publicKey that is not exactly 32 bytes, with a path, the same way #359 moved the consensus-timeout and base-fee range checks into the schema. schemaBytes32 already exists in scripts/genesis/types.ts and is exactly {32} bytes.

Every key in assets/*/genesis.config.ts is already 64 hex characters, so no shipped config changes.

#346, #359 (same class: genesis schema aligned with a runtime check). Does not overlap #374, which normalizes hex casing and leaves the field type alone.

I have a fix ready in #401 and would like to be assigned.
