fix: sanitize tool error results before llm injection (#1639)
* fix: sanitize tool error results before llm injection Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus <[email protected]> * fix: wrap preflight tool rejection errors for llm safety Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus <[email protected]> * style: apply rustfmt to error-path regressions Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent) Co-authored-by: Sisyphus <[email protected]> * 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.
