* style: apply rustfmt to error-path regressions

* fix: preserve wrapped tool errors in history replay

* fix: address review findings on PR #1639

- Simplify legacy error handling in rebuild_chat_messages_from_db:
  remove redundant "Error: " prefix since legacy errors already contain
  descriptive text (e.g. "Tool 'http' failed: timeout"). Both wrapped
  (new) and plain (legacy) errors now pass through as-is.
- Update existing test assertion to match simplified format.
- Restore error-path doc line on process_tool_result.

* fix: satisfy clippy on builder tool safety helper
