Extract Reusable Zod Schema Constants for MCP Tools

[foxintheloop]

Problem

apps/mcp-server/src/tools/tasks.ts duplicates field definitions across createTaskSchema, updateTaskSchema, and bulkCreateTasksSchema (effort_score, impact_score, urgency_score, importance_score, energy_required, etc.).

Solution

1. Extract reusable schema constants: idSchema, dateSchema, scoreSchema, energySchema
2. Use .pick() / .extend() / .partial() for schema variants instead of redefining fields
3. Add .max() limits on all string fields (title: 500, notes: 10000)
4. Add regex validation for date (YYYY-MM-DD) and time (HH:MM) fields
5. Add cross-field validation with .refine() (e.g., due_time requires due_date)
