Struct SummarizingCompaction 

pub struct SummarizingCompaction {
    pub keep_tail: usize,
    pub summarize: Arc<dyn Fn(Vec<Message>) -> Result<String, MachiError> + Send + Sync>,
}

Summarizing compaction: replace dropped prefix with a single summary message.

The summarize callback is synchronous so strategies stay pure-sync; hosts that call an LLM inject a precomputed summary or a blocking adapter.

Fields

keep_tail: usize

Tail size to retain.

summarize: Arc<dyn Fn(Vec<Message>) -> Result<String, MachiError> + Send + Sync>

Build a summary for the compacted-away prefix (excluding system).
