feat: complete agent refactoring integration

- Add deposit session routing to openai-service.ts
- Convert deposit-tool to agent trigger (delegate to deposit-agent)
- Update CLAUDE.md with new agent architecture

Changes:
- openai-service.ts: Import and check hasDepositSession, route to processDepositConsultation
- deposit-tool.ts: Convert action → natural language → delegate to Deposit Agent
- CLAUDE.md: Update Core Services, Function Calling Tools, Data Layer, Deposit System sections

All tests passing (192/195), dev server starts successfully.
