Module context 

Query execution context module

This module provides all context types used during query execution:

• QueryContext: Main context for query lifecycle management
• QueryRequestContext: Request-level context (session, parameters)
• QueryContextBuilder: Builder pattern for constructing QueryContext

Architecture

The context system follows a composite pattern:

QueryContext
├── rctx: QueryRequestContext  (request info, parameters)
├── cancel_token: CancelToken  (request-scoped cancellation, shared with runtime/registry)
├── id_gen: IdGenerator  (unique ID generation)
├── space_info: Option<SpaceInfo>  (current graph space)
└── charset_info: Option<CharsetInfo>  (character set)

Re-exports

pub use query_context_builder::QueryContextBuilder;

pub use query_request_context::QueryRequestContext;
