Separate unit, database, and API integration tests (#997)

* Separate unit and integration tests to allow external contributors

This change addresses the issue where external contributor PRs fail unit
tests because GitHub secrets (API keys) are unavailable to external PRs
for security reasons.

Changes:
- Split GitHub Actions workflow into two jobs:
  - unit-tests: Runs without API keys or database connections (all PRs)
  - integration-tests: Runs only for internal contributors with API keys
- Renamed test_bge_reranker_client.py to test_bge_reranker_client_int.py
  to follow naming convention for integration tests
- Unit tests now skip all tests requiring databases or API keys
- Integration tests properly separated into:
  - Database integration tests (no API keys)
  - API integration tests (requires OPENAI_API_KEY, etc.)

The unit-tests job now:
- Runs for all PRs (internal and external)
- Requires no GitHub secrets
- Disables all database drivers
- Excludes all integration test files
- Passes 93 tests successfully

The integration-tests job:
- Only runs for internal contributors (same repo PRs or pushes to main)
- Has access to GitHub secrets
- Tests database operations and API integrations
- Uses conditional: github.event.pull_request.head.repo.full_name == github.repository

* Separate database tests from API integration tests

Restructured the workflow into three distinct jobs:

1. unit-tests: Runs on all PRs, no external dependencies (93 tests)
   - No API keys required
   - No database connections required
   - Fast execution

2. database-integration-tests: Runs on all PRs with databases (NEW)
   - Requires Neo4j and FalkorDB services
   - No API keys required
   - Tests database operations without external API calls
   - Includes: test_graphiti_mock.py, test_falkordb_driver.py,
     and utils/maintenance tests

3. api-integration-tests: Runs only for internal contributors
   - Requires API keys (OPENAI_API_KEY, ANTHROPIC_API_KEY, etc.)
   - Conditional execution for same-repo PRs only
   - Tests that make actual API calls to LLM providers

This ensures external contributor PRs can run both unit tests and
database integration tests successfully, while API integration tests
requiring secrets only run for internal contributors.

* Disable Kuzu in CI database integration tests

Kuzu requires downloading extensions from external URLs which fails in CI
environment due to network restrictions. Disable Kuzu for database and API
integration tests.

* Use pytest -k filter to skip Kuzu tests instead of DISABLE_KUZU

The original workflow used -k "neo4j" to filter tests. Kuzu requires
downloading FTS extensions from external URLs which fails in CI. Use
-k "neo4j or falkordb" to run tests against available databases while
skipping Kuzu parametrized tests.

This maintains the same test coverage as the original workflow while
properly separating unit, database, and API integration tests.

* Upgrade Kuzu to v0.11.3+ to fix FTS extension download issue

Kuzu v0.11.3+ has FTS extension pre-installed, eliminating the need to
download it from external URLs. This fixes the "Could not establish
connection" error when trying to download libfts.kuzu_extension in CI.

Changes:
- Upgrade kuzu dependency from >=0.11.2 to >=0.11.3
- Remove pytest -k filters to run all database tests (Neo4j, FalkorDB, Kuzu)
- FTS extension is now available immediately without network calls

* Move pure unit tests from database integration to unit test job

The reviewer correctly identified that test_bulk_utils.py,
test_edge_operations.py, and test_node_operations.py are pure unit tests
using only mocks - they don't require database connections.

Changes:
- Removed tests/utils/maintenance/ from ignore list (too broad)
- Added specific ignore for test_temporal_operations_int.py (true integration test)
- Moved test_bulk_utils.py, test_edge_operations.py, test_node_operations.py to unit tests
- Kept test_graphiti_mock.py in database integration (uses real graph_driver fixture)

This reduces database integration test time and properly categorizes tests.

* Skip flaky LLM-based tests in test_temporal_operations_int.py

- test_get_edge_contradictions_multiple_existing
- test_invalidate_edges_partial_update

These tests rely on OpenAI LLM responses for edge contradiction detection and produce non-deterministic results.

* Use pytest -k filter for API integration tests

Replace explicit file listing with `pytest tests/ -k "_int"` to automatically discover all integration tests in any subdirectory. This improves maintainability by eliminating the need to manually update the workflow when adding new integration test files.

Excludes:
- tests/driver/ (runs separately in database-integration-tests)
- tests/test_graphiti_mock.py (runs separately in database-integration-tests)

* Rename workflow from "Unit Tests" to "Tests"

The workflow now runs multiple test types (unit, database integration, and API integration), so "Tests" is a more accurate name.
