Add changefeed triggers for summarization and memory processing

[jcodella]

This pull request introduces comprehensive documentation updates to cover the new automatic processing feature using Cosmos DB change feed triggers. It explains how the toolkit can now automatically process thread summaries, fact extraction, and user summaries in the background, based on configurable thresholds. The changes also provide setup instructions, troubleshooting steps, and usage examples for both local and Azure environments. Additionally, the .github/CODEOWNERS and CI workflow files are removed.

Major documentation improvements:

• Added detailed explanations of automatic processing via the Cosmos DB change feed trigger, including how it works, required configuration, threshold settings, and when to use automatic vs. on-demand processing (Docs/concepts.md, Docs/design_patterns.md, Docs/README.md) [1] [2] [3] [4] [5].
• Updated local and Azure testing guides to include setup and validation steps for change feed auto-processing, including configuration examples, test code, and troubleshooting tips (Docs/local_testing.md, Docs/azure_testing.md) [1] [2] [3] [4] [5] [6] [7] [8] [9].

Design pattern and usage updates:

• Expanded the design patterns documentation to show how automatic processing integrates with existing CRUD, summarization, and fact extraction workflows, with clear references to the new feature (Docs/design_patterns.md) [1] [2] [3].

Project configuration and maintenance:

• Removed the .github/CODEOWNERS file, eliminating required reviewers for all changes.
• Removed the .github/workflows/ci.yml file, disabling the existing GitHub Actions CI pipeline.

These updates ensure users and developers can leverage the new automatic processing capabilities and have clear guidance for setup, testing, and troubleshooting.

Pull request overview

Adds Cosmos DB change feed–driven “automatic processing” for the Azure Functions pipeline (thread summaries, fact extraction, user summaries) using per-scope counter documents + threshold crossings, and updates docs/samples/tests accordingly. Also removes GitHub repo governance/automation files.

Changes:

• Implemented on_memory_change Cosmos DB trigger + counter/threshold helpers and extracted batch-processing logic for testability.
• Added unit + integration tests covering threshold logic, counter retries, and basic end-to-end counter increments.
• Expanded documentation and the demo notebook to explain/configure/validate change feed auto-processing; updated local settings template; removed CI workflow and CODEOWNERS.

tests/unit/test_changefeed.py:1

• The new FACT_EXTRACTION_EVERY_N threshold path (starting the orchestrator with extract_facts_only) isn’t covered by the added unit tests, while the analogous thread-summary and user-summary paths are. Add a test case that sets FACT_EXTRACTION_EVERY_N > 0, returns an (old,new) pair that crosses the facts threshold, and asserts starter.start_new is called with extract_facts_only.

"""Unit tests for the change feed trigger helpers and batch logic in function_app.py."""
