feat(agents): add 7 specialist agents with tools and system prompts

Agents (all following 6-step contract: _plan/_gather/_reason/_act/_report):
- AccountingAgent: trial balance, chart of accounts, tax summary (HIPAA-locked)
- CrmAgent: pipeline summary, lead/opportunity management, won/lost analysis
- SalesAgent: sales orders, quotations, revenue by rep, expired quote detection
- ProjectAgent: task tracking, blocked/overdue detection, timesheet logging
- ElearningAgent: course completion, low-engagement flagging, next-course suggestion
- ExpensesAgent: expense sheets, pending approvals, policy violations (HIPAA-locked)
- EmployeesAgent: headcount, contracts, leaves, attendance, expired contract sweep (HIPAA-locked)

Tools (one file per domain):
- accounting_tools.py, crm_tools.py, sales_tools.py, project_tools.py
- elearning_tools.py, expenses_tools.py, employees_tools.py

System prompts: each agent has a domain-specific system.txt with rules and output format

All agents implement handle_peer_request() and sweep() for proactive monitoring
HIPAA-locked agents (accounting, expenses, employees) enforced via LLMRouter
