George WealeandCopybara-Service a88e864755 fix: Add post-invocation token-threshold compaction with event retention ...

Adds optional token_limit and event_retention_size fields to EventsCompactionConfig. When the latest prompt token count meets/exceeds the threshold, ADK compacts older raw events after the invocation and keeps the last N events un-compacted. Updates prompt history building to apply compaction ranges correctly so retained events remain visible.

Close #4146
