feat: [#246] use NonZeroU32 for Prometheus scrape interval domain model
BREAKING CHANGE: Prometheus configuration now uses type-level guarantees Domain Layer Changes: - Use NonZeroU32 instead of u32 with runtime validation - Add DEFAULT_SCRAPE_INTERVAL_SECS constant (15 seconds) - Rename field: scrape_interval -> scrape_interval_in_secs - Constructor is now infallible (const fn) - Remove PrometheusConfigError enum (no longer needed in domain) Application Layer (DTO): - Add PrometheusSection DTO with u32 for JSON deserialization - Validation happens at DTO -> Domain boundary - to_prometheus_config() converts u32 -> NonZeroU32 - Maps conversion errors to CreateConfigError::InvalidPrometheusConfig Benefits: - Type-level guarantee: impossible to construct invalid config - Zero-cost abstraction: same memory layout as u32 - Simpler domain logic: no runtime validation needed - Clear intent: type documents non-zero requirement - Single source of truth: DEFAULT_SCRAPE_INTERVAL_SECS constant Schema Updates: - Change scrape_interval from string to integer - Update field name to scrape_interval_in_secs - Add minimum: 1 constraint in JSON schema Template Updates: - Template still expects integer (15 -> "15s") - No template changes needed Testing: - All 1554 unit tests passing - E2E tests verified: Prometheus deployed and running - Manual verification: scrape interval correctly set to 15s - Metrics collection working (both tracker_metrics and tracker_stats) - HTTP health checks passing on port 9090 Co-authored-by: GitHub Copilot <[email protected]>
