Module helpers 

Pure helper functions for context assembly.

These functions are called by assembly.rs in zeph-core (via a module alias) and by the crate::service::ContextService stubs that will be filled in during subsequent migration steps.

All functions operate on crate::state::ContextAssemblyView instead of the zeph-core-internal MemoryState, keeping this crate free of zeph-core types.
