Struct SelectiveToolResult 

pub struct SelectiveToolResult {
    pub keep_last: usize,
}

Replace the payload of Content::FunctionResult (tool-result) content in all but the last keep_last messages that carry tool results — they are the bulkiest and least useful once stale. Text and other content is left intact.

The result content itself is kept, with its payload swapped for OMITTED_TOOL_RESULT — on result and, for a failed call, on exception too, since provider converters render exception instead of result and leaving it would send the original error verbatim — rather than deleted. Deleting it would leave the matching assistant tool_calls entry unanswered, which providers reject outright — so the size win would come at the cost of a 400 on the next request. Mirrors the intent of upstream’s ToolResultCompactionStrategy, which likewise replaces stale tool groups with a compact stand-in instead of removing them; upstream summarizes the group with an LLM, while this port (which has no summarizing strategy) substitutes a fixed marker.
