PR: Add Terminal CLI for Polkadot Agent Kit

Overview

This PR introduces a fully-featured terminal CLI (@polkadot-agent-kit/cli) for managing and interacting with AI agents on the Polkadot network. The CLI enables users to create, configure, and run agents, perform blockchain operations, and interact with agents in an interactive chat session—all from the command line.

---

Key Features

• Agent Management

  • Create new agents with private key or mnemonic import, key type selection, and network selection (all or specific chains).
  • List, delete, and update agent configurations.
  • Store agent metadata and configuration securely on disk.

• Blockchain Operations

  • Check balances on supported chains.
  • Transfer tokens (native and XCM/cross-chain).
  • Swap tokens using DEX protocols.
  • Staking operations (join pool, bond extra, unbond, withdraw, claim rewards).

• Interactive Chat

  • Start a chat session with an agent in the terminal.
  • Natural language commands are parsed and routed to the appropriate blockchain tools (balance, transfer, xcm, swap, etc.).
  • Unified system prompt ensures consistent agent behavior and clear instructions.

Example Usage

# Create a new agent interactively
pak agent create my-agent --interactive
