CLI fails to parse private key with 0x prefix

[Radiiplus]

Description

The offckb deploy command fails to accept private keys with the standard 0x prefix.

Error

Error: Private key must be 32 bytes! at new SignerCkbPrivateKey(...)

Reproduction

# This fails even with valid 32-byte key
offckb deploy --network devnet --target ./my-contract --privkey 0x1234...abcd -y

# This works (manually stripped prefix)
offckb deploy --network devnet --target ./my-contract --privkey 1234...abcd -y

Expected Behavior

The CLI should accept private keys with or without the 0x prefix, as this is the standard format used in .env files and other CKB tooling.

Environment

• offckb CLI version: latest
• OS: Linux (WSL2)

Impact

Users must manually strip the 0x prefix before using the CLI, which is error-prone and inconsistent with other CKB tools.
