- Remove 80-char truncation from bash command summaries in summarizeToolArgs
- Remove length guard from fallback string-valued arg path
- Update agent-logger tests to expect full strings without truncation
- Add test case for long string-valued fallback args
- Update executor tests to match new non-truncating behavior
