fix: color execution time based on duration in verbose mode (#680) (#681)

* fix: color execution time based on duration in verbose mode

In verbose mode, execution time was always displayed in cyan (blue).
Now uses a color palette to help spot slow operations:
- ≤1s: green (fast)
- 1-5s: cyan (normal)
- 5-30s: yellow (slow)
- ≥30s: red (very slow)

Fixes #680
