feat: timer indicator for spinner

[mdjastrzebski]

Summary

Adds spinner option for showing timer instead of animated dots at the end ... .

spinner() // defaults to dots for compatibility
spinner({ indicator: `dots` }) // explicitly set dots
spinner({ indicator: `timer` }) // enable timer indicator

Manually adding timer (or any other custom progress indicator) results in too verbose logging on CI, as each partial update results in new spinner message.

Visualization

CleanShot.2025-01-27.at.16.47.37.mp4

Testing

Run pnpm spinner-timer in examples/basic. Also check spinner and spinner-ci to ensure that default behavior is not broken.

Discussion points

1. This could alternatively be implemented as a more general progress indicator where user would provide the indicator callback to run and which would be ignored by the CI.
2. Should ... loading dots be kept when timer is running? Currently they have a different cadence, which creates a weird effect. If we were to keep them it would make sense to sync them to the timer, i.e. one do per second (or maybe 1/2 second)
