fix: silence ChromaDB telemetry warnings and CoreML segfault on Apple Silicon

ChromaDB 0.6.x bundles a Posthog telemetry client whose capture()
signature is incompatible with the installed posthog library, producing
noisy "Failed to send telemetry event" stderr warnings on every
operation. Silence by raising the logger threshold to CRITICAL.

ONNX Runtime's CoreML execution provider segfaults during vector
queries on macOS ARM64 (issue #74). Auto-set ORT_DISABLE_COREML=1
on Apple Silicon to force CPU execution, while respecting any
user-provided override via os.environ.setdefault().
