sketch: dump message history to /tmp on conversation compaction and include filename in summary

Add dumpMessageHistoryToTmp method that dumps complete agent message history to timestamped JSON file during conversation compaction, returning filename for inclusion in compaction summary message.

When conversation compaction occurs, the agent now:
- Dumps entire a.history array to /tmp/sketch-messages-{sessionID}-{timestamp}.json as formatted JSON
- Returns filename from dumpMessageHistoryToTmp for reference in summary message
- Includes dump file location in compaction summary: "The complete message history has been dumped to {filename} for your reference if needed"
- Continues compaction process even if dump fails to avoid blocking conversation flow

Implementation:
- Added dumpMessageHistoryToTmp method returning (filename, error)
- Modified CompactConversation to call dump before generating summary
- Enhanced summary message to conditionally include dump file reference
- Uses 2-space JSON indentation for readability and 0644 file permissions
- Creates timestamped filenames to avoid conflicts across multiple compactions

The implementation provides access to complete conversation history during epoch restarts while maintaining conversation compaction benefits.
