Extra Effect Schema codecs for hex strings.

Branded, decode/encode-ready schemas with generated arbitraries:

• HexString — a 0x-prefixed hex string.
• PrefixedHex — prefixed hex with length constraints.
• StrictHex — bare hex (no prefix).
• ColonHex — colon-separated hex octets.

import { HexString } from '@systemfsoftware/effect-schema-extensions'
import { Schema as S } from 'effect'

const decode = S.decodeUnknownSync(HexString)
decode('0xdeadbeef') // branded HexString
