feat: edge prompt + session resume implementation (#402)

- buildContinuationPrompt: incremental prompt for role re-entry
- buildHermesPrompt: dual-mode (initial vs continuation)
- session-cache: thread:role → hermes sessionId mapping
- HermesAcpClient.resume(): session/resume JSON-RPC
- Fallback: cache miss or resume fail → initial prompt
- UWF_NO_RESUME env to skip cache
- solve-issue.yaml: reviewer→developer edge prompt
- Tests updated for EvaluateResult + continuation prompt
