Function create_session_context 

pub fn create_session_context() -> SessionContext

Creates a DataFusion session context with identifier normalization disabled.

Suitable for ad-hoc / non-streaming queries (filters, lookups). For streaming workloads prefer create_streaming_context. This standalone factory uses upstream unbounded memory and disk-manager defaults. It does not share a LaminarDB budget; use SessionContext::new_with_config_rt with a caller-owned runtime when reservation limits are required.
