merge: Address several regressions in simulator

This pull request addresses several regressions that have been introduced in the past few pull requests.

- Fix queue resizing logic
- Change clock resolution from milliseconds to nanoseconds in `OtelClockAdapter`
- Compute energy usage in absence of convergence
- Fix duplicate classpath entries
- Fix release workflow

**Breaking API Changes**

- `OtelClockAdapter` now exports time in nanoseconds as the method contract describes.
