BREAKING CHANGE: None - fully backward compatible Changes: - feat(notifications): extend JSON templates to Discord, Slack, Gotify, and generic - fix(uptime): resolve race conditions and false positives with failure debouncing - chore(tests): add comprehensive test coverage (86.2% backend, 87.61% frontend) - docs: add feature guides and manual test plan Technical Details: - Added supportsJSONTemplates() helper for service capability detection - Renamed sendCustomWebhook → sendJSONPayload for clarity - Added FailureCount field requiring 2 consecutive failures before marking down - Implemented WaitGroup synchronization and host-specific mutexes - Increased TCP timeout to 10s with 2 retry attempts - Added template security: 5s timeout, 10KB size limit - All security scans pass (CodeQL, Trivy)
