test: add 13 targeted tests for 80%+ Codecov patch coverage

ToolErrorInterceptor: 100% line coverage (up from 92.63%)
- resetTaskState both paths (with/without category)
- transformError both paths (classified/unclassified)
- isErrorResult Error:/error: prefixes
- inferStatus denied/undefined branches

presentAssistantMessage: 90.44% diff-line coverage (up from 27.51%)
- Validation error classification (modeRestriction, unknownTool, fileRestriction)
- Tool repetition detection guided payload
- Unknown tool handling guided payload
