Module summarization 

Pure prompt-building, compaction helpers, and async LLM summarization for context.

Stateless functions take only Message slices and configuration values; they contain no agent state access. The SummarizationDeps struct provides explicit LLM dependencies for the async summarization functions, avoiding coupling to Agent<C>.

The orchestration layer (Agent::compact_context, Agent::maybe_compact, etc.) lives in zeph-core and calls these helpers.

Structs
