From 5c247f3ed20c46ad98449daed06e7f821bc515d9 Mon Sep 17 00:00:00 2001 From: Matthew Raymer Date: Fri, 3 Oct 2025 06:24:54 +0000 Subject: [PATCH] refactor(web): simplify web implementation by removing excessive Service Worker complexity - Remove IndexedDB-based Service Worker implementation (sw.ts) - Remove Service Worker manager (service-worker-manager.ts) - Simplify web.ts to use immediate operations and in-memory caching - Fix TypeScript compilation errors from complex Service Worker types - Preserve core plugin API functionality while reducing complexity - All tests pass (58/58) and build compiles successfully Resolves TypeScript build issues that emerged after merge. TimeSafari integration will use platform-specific storage solutions.
