chore: clean up unused code and fix test imports

- Remove unused config in commands.ts
- Remove deprecated formatDepositResult function in deposit-tool.ts
- Remove unused type imports in deposit-tool.ts
- Fix import path in deposit-agent.test.ts (src/deposit-agent → src/agents/deposit-agent)

This is a cleanup commit following the agent pattern unification work.
