Keep embedded test data off system temp dirs

[hnwyllmm]

Summary

• keep embedded SeekDB test data under a configurable SEEKDB_TEST_DATA_ROOT
• place GitHub Actions test data in the checked-out workspace instead of runner.temp
• create multiprocess embedded databases under the configured test-data root
• ignore the generated workspace-local test-data directory

Root cause

Some CI hosts mount the system temporary directory as tmpfs. SeekDB opens its block file with O_DIRECT, so placing an embedded database there fails with EINVAL before the server becomes ready.

Impact

This is a test-only workaround. Runtime client behavior is unchanged, and callers can override the test location with SEEKDB_TEST_DATA_ROOT.

Validation

• ruff check passed
• ruff format --check passed
• related unit tests: 14 passed
• embedded multiprocess tests: 7 collected
• real embedded smoke test with pylibseekdb 1.3.0.post1: 1 passed
• git diff --check passed

Summary by CodeRabbit

• Tests
  • Improved integration test database configuration with a dedicated, configurable data directory.
  • Test databases now use consistent workspace-local storage instead of repository-root or system temporary locations.
• Chores
  • Added test data directories to ignore rules to prevent generated files from being tracked.

📝 Walkthrough

Walkthrough

Integration test database files now use a configurable SEEKDB_TEST_DATA_ROOT. The default is .seekdb-test-data, and CI sets the same workspace-local path. Multiprocess test databases are created within this directory.

Changes

Integration test data storage

Layer / File(s)	Summary
Configure the shared test data root .github/workflows/ci.yml, .gitignore, tests/integration_tests/conftest.py	CI sets SEEKDB_TEST_DATA_ROOT. Test configuration derives SEEKDB_PATH from this directory. Git ignores the default directory.
Place multiprocess databases under the data root tests/integration_tests/test_get_or_create_collection_multiprocess.py	The multiprocess tests read SEEKDB_TEST_DATA_ROOT and create embedded database directories inside it.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to 95d8e

The change keeps embedded test data in a configurable workspace location, but a failed multiprocess test setup can leave temporary database directories behind and gradually consume workspace disk. The PR is mergeable with owner awareness and follow-up to clean up this failure path.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Clean up the temporary directory when setup fails.

If _make_admin_client() or admin.create_database(database) raises after tempfile.mkdtemp(), _build_client_config() exits before multiprocess_db() reaches its cleanup at Lines 526-530. Repeated setup failures can leave seekdb-mp-* directories in the workspace and consume disk space. Remove temp_db_path in an exception path before re-raising.
