Sequentially ce metrics

[stasimus]

Add SequentiallyMetricsF and MeteredSequentiallyF with comprehensive test coverage

• Add SequentiallyMetricsF: Prometheus metrics tracking for SequentiallyF operations

  • Factory pattern for creating metrics instances with configurable prefixes
  • Queue time and run time metrics recording
  • Support for custom metric names and labels

• Add MeteredSequentiallyF: Wrapper around SequentiallyF with integrated metrics

  • Delegates to SequentiallyF while adding metrics tracking
  • Supports both apply (Future-based) and applyF (F-based) APIs
  • Records queue and run metrics for all operations

• Add comprehensive unit tests:

  • SequentiallyMetricsFSpec: 15+ test cases covering factory, metrics recording,
    exception handling, and integration scenarios
  • MeteredSequentiallyFSpec: 13+ test cases covering sequential/parallel execution,
    metrics integration, exception handling, and factory pattern

• Fix MeteredSequentiallyF compilation issues:

  • Rename second apply method to applyF to avoid ambiguity
  • Fix metrics integration to use applyF instead of apply
  • Properly handle Future-based apply with metrics

• Add test dependencies:

  • Scalatest % Test to sequentially-ce-metrics module
  • CatsEffect.effect for IO-based testing

• Rename SequentiallyCatsSpec to SequentiallyFSpec for consistency

All tests compile successfully for Scala 2.13 and 3.3.6.
