2eee030616 Add Letta Cloud-only warning to SDK v1.0 migration guide (#6153) 
* Add Letta Cloud-only warning to SDK v1.0 migration guide

Added prominent warning at the top of the SDK v1.0 migration guide to clarify that:
- SDK v1.0 is only supported on Letta Cloud
- Self-hosted Letta v0.13.x does NOT support SDK v1.0
- Users should continue using SDK v0.x with self-hosted until future releases

This prevents confusion for self-hosted users trying to upgrade to SDK v1.0.

👾 Generated with [Letta Code](https://letta.com)

Co-Authored-By: Letta <noreply@letta.com>

* Add note about upcoming OSS release with SDK v1.0 support

Updated the warning to mention that a new open-source release with SDK v1.0 support is coming soon for self-hosted users.

546c972d2e Simplify docs navigation to 3 tabs (#5940) 
* Add archival memory import/export utilities

Added two utility scripts for managing agent archival memories:

- export_agent_memories.py: Export all passages from an agent to JSON
  - Paginates through all results
  - Removes embedding/embedding_config for portability
  - Usage: python export_agent_memories.py <agent_id> [--output <file>]

- import_agent_memories.py: Import passages into an agent from JSON
  - Batch imports with progress tracking
  - Handles optional fields (tags, created_at)
  - Includes dry-run mode for preview
  - Usage: python import_agent_memories.py <agent_id> <input_file>

Use cases:
- Backup/restore agent memories
- Transfer memories between agents
- Seed new agents with existing knowledge bases

Co-Authored-By: Letta <noreply@letta.com>

* Reorganize docs navigation structure

- Move 'Legacy & Migration' and 'Research Background' under 'Additional Resources'
- Restructure Tools section with clearer hierarchy:
  - Using Tools (basics)
  - Built-in Tools (prebuilt utilities)
  - Advanced Configuration (rules, variables)
  - Model Context Protocol (integrations)
- Remove awkward 'Utilities' subsection
- Create more logical progression from basics to advanced

* Reorganize docs with task-based structure

Instead of organizing by technical concepts (Memory, Tools, Configuration),
reorganize by user goals and tasks:

1. Building Agents
   - Agent basics & fundamentals
   - Adding Memory (all memory content together)
   - Adding Tools (all tool content together)
   - Multi-modal & structured output

2. Working with Data
   - Files & Filesystem
   - Import/Export workflows
   - Memory export

3. Controlling Behavior
   - Tool rules & workflows
   - Execution controls (streaming, long-running)
   - HITL, scheduling

4. Connecting Systems
   - MCP
   - Multi-user
   - Multi-agent
   - Integrations

5. Experimental Features
   - Groups, sleep-time agents, voice

Benefits:
- Clearer user journey from basics to advanced
- Related content grouped by task, not type
- Easier to find 'how do I...' answers
- Flatter hierarchy, less nesting

* Simplify docs navigation to 3 tabs

Consolidated docs.yml to have only 3 main tabs:
- Developer Guide (all guides and tutorials)
- Examples (cookbooks and tutorials)
- API Reference (API docs)

Removed duplicate tab navigation entries for cloud, showcase, evals, examples, and ref tabs.

👾 Generated with [Letta Code](https://letta.com)

Co-Authored-By: Letta <noreply@letta.com>

* Reorganize Advanced Features into logical sections

Moved items from Advanced Features section to more appropriate locations:
- Tool-related items → Adding Tools section
- Agent capabilities (streaming, long-running, etc.) → New Agent Capabilities section
- Configuration items (multi-user, scheduling, agent files) → New Configuration section
- Multi-Agent Systems → Top-level section under Building Agents
- Experimental features → Top-level section under Building Agents
- Exporting Archival Memories → Added to Archival Memory section
- MCP → Added under Adding Tools

Removed the Advanced Features section entirely.

* Create Application Integration section

Renamed "Agent Capabilities" to "Application Integration" and moved appropriate items:
- Streaming Responses
- Long-Running Executions
- Human-in-the-Loop

Kept under Building Agents:
- Multi-Modal Inputs
- JSON Mode & Structured Output
- Files & Filesystem

This better separates agent features from application integration concerns.

👾 Generated with [Letta Code](https://letta.com)

Co-Authored-By: Letta <noreply@letta.com>

* Move Message Types to Application Integration

Message Types is more about understanding API message formats for integration rather than building agent capabilities.

👾 Generated with [Letta Code](https://letta.com)

Co-Authored-By: Letta <noreply@letta.com>

* Add missing evals pages and fix all broken links

Added missing evals documentation pages to navigation:
- Core Concepts: Gates
- Graders section: Tool Graders, Rubric Graders, Multi-Metric
- Extractors section: Built-in, Custom
- Advanced section: Custom Graders, Multi-Turn Conversations
- CLI Reference: Commands
- Troubleshooting: Common Issues

Fixed 83 broken links across documentation:
- Evals internal links (updated paths to /guides/evals/...)
- Cloud documentation links (/guides/cloud/...)
- Concept documentation links (legacy memgpt paths)
- Getting started links (composio, quickstart, ade setup)
- Agent documentation links (archival-memory, multiagent, human-in-the-loop)
- Examples links (pdf-chat, shared-memory-blocks, multi-agent-async)
- Changelog API reference links
