Sub-Module Unit Tests & Shared Concern Tests

What Was Built

Created isolated unit tests for the extracted FeedFetcher sub-modules (AdaptiveInterval, SourceUpdater) that were refactored in Phase 3 but never received dedicated test files. Created a SharedLoggableTests module that validates the Loggable concern contract and included it in all 3 log model test files (FetchLog, ScrapeLog, HealthCheckLog). Added 64 new tests across 5 new/updated files. Full suite passes at 1622 runs, 0 failures.
