description	Run tests. Use after code changes to validate. Arguments: unit (default, no GPU), e2e (with models), filter name, or all.

Test

Run unit and/or E2E tests.

• unit (default): Quick tests, no model downloads. CI-safe.
• e2e: Full pipeline tests with real models, via scripts/test_e2e_isolated.sh — one process per E2E suite. Never use plain swift test for the full E2E suite: models accumulate in a single xctest process and can exhaust system memory (observed: machine reboot).
• all: Both unit and E2E (unit phase once, then isolated E2E suites).
• Any other argument: passed as --filter to swift test.

E2E test classes MUST be prefixed with E2E. Unit test classes must NOT contain E2E.
