Add Temporal Cortex calendar scheduling quickstart

[billylui]

Summary

Adds a quickstart notebook for building a conflict-free calendar scheduling agent using CrewAI + Temporal Cortex MCP server.

The notebook demonstrates:

• 3-agent crew mapped to Temporal Cortex's tool layers (temporal context, calendar ops, booking)
• Deterministic datetime resolution — resolve_datetime instead of LLM guessing
• Cross-provider availability merging — Google + Outlook + CalDAV in a single view
• Atomic booking — Two-Phase Commit via book_slot prevents double-bookings
• Native MCP integration — zero custom code, uses MCPServerAdapter for auto tool discovery

Unlike basic CRUD calendar integrations, Temporal Cortex provides deterministic temporal reasoning (LLMs score <50% on temporal tasks per the OOLONG benchmark). The notebook covers stdio transport (local), Platform Mode (SSE), and the DSL mcps approach.
