🚀 v2026.1.0 — CalVer Versioning + Context Management

This release marks a major milestone with Calendar Versioning (2026.MINOR.PATCH) for a more modern, predictable release cadence.

🆕 What's New

📊 Chat History Context Management

The get_notebook_chat_history tool now includes powerful context management to prevent overwhelming your AI context window:

| Feature | Use Case |
|---------|----------|
| preview_only: true | Quick audit — returns counts without content |
| output_file: "/path/file.json" | Export to disk instead of context |
| offset + limit | Paginate through large histories |

Examples:

// Preview mode - test the water
{ "notebook_id": "my-research", "preview_only": true }

// Export to file - avoid context overflow  
{ "notebook_id": "my-research", "output_file": "/tmp/history.json" }

// Paginate - page through history
{ "notebook_id": "my-research", "limit": 20, "offset": 0 }

Enhanced Response Data

{
  "total_messages": 150,
  "returned_messages": 40,
  "user_messages": 75,
  "assistant_messages": 75,
  "offset": 0,
  "has_more": true,
  "messages": [...]
}

📅 CalVer Versioning

We've switched from semver (1.10.x) to Calendar Versioning:

| Format | Example | Meaning |
|--------|---------|---------|
| YYYY.MINOR.PATCH | 2026.1.0 | Year 2026, 1st feature release, 0 patches |

This aligns with MEDUSA and provides clearer release timelines.
