feat: integrate OpenTelemetry Metrics API

Add pluggable metrics collection using OpenTelemetry standard, allowing
applications to export Raft metrics to any OTEL-compatible backend
(Prometheus, Jaeger, OTLP, etc.).

Changes:
- Add `MetricsRecorder` trait with histograms, gauges, and counters
- Add `metrics-otel` crate with `OpenTelemetryRecorder` implementation
- Add `Raft::set_metrics_recorder()` API to install custom recorder
- Add `RaftTerm::as_u64()` for optional term-to-u64 conversion
- Support all integer types for `RaftTerm`
- Add comprehensive tests for all `MetricsRecorder` methods

- Fix: #1446
