fix(diagnosis): tighten timeout handling and clarify timeout messaging (#233)

## Summary
- shorten per-item diagnosis command timeout from 2 minutes to 30
seconds while keeping overall request timeout at 2 minutes
- centralize timeout messages in backend constants and apply consistent
timeout fallback handling in diagnosis result assembly
- update frontend forward/tunnel diagnosis timeout copy to clearly
explain single-item and overall timeout limits

## Notes
- includes workspace tool config files under `.claude/` and `.entire/`
as part of this commit
