Fixes #2375
This PR addresses the issue where the
heartbeatsession accumulates tasks over time, leading to massive token consumption (up to 560k tokens) and eventual context overflow.Since the heartbeat is a stateless background task that doesn't need to remember its past executions, this PR simply clears the
heartbeatsession immediately afterprocess_directcompletes. This ensures the session remains clean and token usage stays minimal.This approach is similar to how
ironclawhandles routine notifications (nearai/ironclaw#1524), by preventing background tasks from polluting the long-term context.
