Replace custom buildHistorySummary with shared buildContinuationPrompt
from workflow-agent-kit. This aligns claude-code agent with hermes agent:
- First visit: includes step content (within 32k quota)
- Re-entry: shows only steps since last visit (meta only, session has context)
Previously developer could not see reviewer's detailed feedback on
re-entry, only {"approved":false}. Now gets full review text.
Fixes #486
